I was just looking at LCA and bushing threads tonight and saw one of the ones you're probably talking about, posted back in February. Lower control arm bushings?

Greg told me that this didn't work out. Bent a LCA trying to press them out. The entire LCA can be replaced for around $167 each, plus shipping.

Below is a link to a thread on the LCA ball joint replacement using Moog ball joints with the grease fittings. They are around $100 a piece, but it looks like the Nissan ones come with the LCAs. Titan problem solvers

PRG Delrin Lower Control Arm Bushings

PRG LCA Bushing Tool


.

 

As far as I know he doesnt make bushing just Delrin spacers, which I have. All they do is prevent the side to side clank of the arm hitting the pocket because of the stock rubber bushing. I noticed my front end felt a lot more stable once I put them in, the only problem is he designed them for arms that have been used and the bushings worn down. I installed them on my almost new arms so they were really squeaky tell the rubber wore down, now they are fine.

 

So the Delrin Spacers will work with with the Factory LCA's and Bushings? I've had this popp'n noise that's been driving me nutty. I finally pin-pointed it to the LCA's moving forwards and backwards(lay'n under the truck with someone driving over me). :ftard: I know i know sounds like a good way to die. I was desperate. Anyway the LCA's were slamming forward and making my noise. I've tried Silicone lube and tightening to no avail. Can someone enlighten me to this Spacer procedure please. Thanks in advance.

So i talked to Greg at PRG this morning and low and behold he said the Lower Control Arms are designed to move back and forth. He said i won't sell you something you just don't need(imagine that customer service concept). He said that's just not the way i do buisness. He also informed me that the Delrin Spacers he sells were never intended to take out this to and fro play out in the first place. He stated "i don't know when and who decided that's what they are for but they are not". After about a 1/2hr conversation with him and various scenerios he gave me a boatload of info and things to check. After our conversation i went thru the list of things to check and WAALAA i found one of the adjuster cam bolts on the LCA's was a little loose. I had checked them before but i guess i hadn't put enough a$$ behind the breaker bar. Noise gone. I have always heard on here how nice and informative Greg at PRG was but that was simply an understatement. He is great and took alot of his precsious time to steer me in the right direction. I wish you guys/gals could see the smile on my face. Problem solved and didn't cost a dime. Can't beat that. See Ya.

 

So all you did is tighten up the camber bolts and it went away I have the same sound and was gonna order some of those derlin spacers

 

Quite simply, yes. Greg said 99% of the time the guys/gals that think they have worn out their lower control arms are mistaken. The back-n-forth movement of the LCA's is supposed to be there and the Delrin Spacers were never designed to fix that issue. I got under the truck with it jacked up on stands and used a 1/2" drive breaker bar with a 19mm and cheater bar and put some a$$ behind it. Almost all of the adjuster nuts went another 1/4 to 1/2 turn. Put the truck back down and i couldn't make it clank. As stated in my first post, i laid under the truck while the truck rocked back-n-forth and i actually saw the adjuster bolt move side-2-side(this was my 2nd time under the truck this way after talking to Greg). The Adjuster bolts should NOT move at all.

I will add that Greg also said the primary cause of the popping clanking sound on most of the trucks is the steering rack is either loose or bad. It is most common with lifted trucks. I was praying the whole time that i wasn't gonna have to replace the darn rack-n-pinion!!!

 

sorry to bring up an old thread, but if the spacers were not meant to stop the movement in lcas, what are they for ? I just put a brand new rack in this week and I still have that popping noise and it is terrible ! Im going to try to tighten those bolts but if that doesnt help what will ? and what exactly do the spacers do ???

 

What are these then?

I'm concerned that my Cam Bolts are siezed up in my LCA's and I'm gonna have to cut them to get them off. Was thinking of just replaceing the LCA bushings instead of the entire LCA's. New Cam Bolts too obviously

 

Those are brand new ... has the tool to remove the old bushing now too PRG Products



As for the Delrin spacers ...

sorry to bring up an old thread, but if the spacers were not meant to stop the movement in lcas, what are they for ? I just put a brand new rack in this week and I still have that popping noise and it is terrible !

They were designed to take up the fore/aft slack of the stock LCA bushings. these really can make a big difference on bracket lifted trucks as the brackets are often not perpendicular to ...the arms and the stock rubber wear pad will wear in one spot making a noise under braking or sharp bumps.

 

Greg and I have had some discussions around this knocking sound with coilovers. We know it's not the coilovers as the knocking sound is over the small bumps with previous coilovers and the current ones I have on now. Plus, the lifted coilovers were rebuilt by Glen himself and there was nothing wrong with them.

What Greg and I have determined was with the 08+ models the LCAs (especially passenger side) actually makes a clicking/popping sound when moving them up/down when re mounting them on when putting on drop bracket lifts. We are thinking along the lines this sound is being transferred though the coilovers causing the knocking sound in the cab of the truck. Stock shocks and Bilsteins actually mask the sound due to all the rubber mounting on the the shocks. This is why when folks take the coilovers off and put the Bilsteins or stock shocks back on the noise goes away.

Greg is suppose to be putting on his new LCA bushing on his Titan has he has the same knocking sound (just not as bad as some of us). This was suppose to have happened last week to this week but he's tough to get a hold of after the holidays.

So it's clear, the knocking sound is with any coilovers even with no drop bracket lifts installed.

Soon as is peak or hear from Greg to determine if he's complete his LCA bushings I will post something.

 

Awesome! I've been struggling with this noise for awhile now with my Radflo's. Went back to my saggy, worn-out stock struts and the noise went away but as you said, there's a lot of rubber throughout the stock strut. I've been suspecting the LCA bushings for awhile now, but it bothered me that they wouldn't make noticeable noise even with the stock struts on there. I'm *VERY* interested to hear what you find out from Greg.

Initially Greg thought my coilovers had a bad set of upper bearings which he sent me replacements for & I replaced, but the noise persists. The bearings I took out were actually fine and had zero wear. Everything is very tight so the only things left are control arm bushings, ball joints or the coilovers themselves. LCA bushings remain at the top of my suspect list at the moment. I'll wait to hear what you find out from Greg before I consider replacing the bushings or the LCAs themselves.

Speaking of that, has anyone had any success in reducing/eliminating the noise after replacing LCAs with an aftermarket LCA with different/better bushings?

 

I have tried calling Greg each day this week and emailed him 3 times with no luck. I will try again today after 9am PST.

 

Any updates?

It's definitely worse in cold weather FWIW. That could also point to bushings.

 

My Radflos are also making the clunking sound. Can't wait to see what Greg says, hopefully it is just the lca bushings.

 

No luck in reaching Greg as of yet. interesting cause I always have seemed to get a hold of him.
I also posted on his Facebook page, but appears his not responding to anyone's post there either.

I like Greg, very nice person and knows his stuff but the customer service is par a best.

I will try again and get a hold of them this week.

Totally agree on that one. Once you get him on the phone, he's easily one of the best & most well informed guys I've spoken with from any business, but it shouldn't be this hard to get a response of some kind. I saw his long comment awhile ago on Facebook about not compromising personal support, but I'm sure there's a huge portion of his work & support requests that could easily be handled by other people while only the more in-depth & challenging questions/work could go to him.

Good luck in reaching him & definitely update us when you can.

 

I will have to agree. Greg is an awesome guy and PRG products are top notch, but the customer service could use some more effort. I think most companies would welcome customers who are spending big bucks on aftermarket parts.

 

Talked to Greg today and he still hasnt had time to put the bushing in to see if thats the fix, but the good news is I have a set in the mail and will have them installed this weekend to know if that's the fix. Ill keep everyone updated

 

Did you purchase the extraction tool as well?

 

im having my delrin spacers installed tomorrow while my truck gets new tie rods... I have coil over so ill let you all know if it helps...

 

I already have the delrin donuts installed, yes I have the tool coming also, well just the pressing pieces, I have the all thread at my work

 

did you notice a difference with the spacers ?

 

Depends on your problem, they help with worn out bushings but mine were almost brand new when I installed them. The clunk im working on deals with pretty much 08+ and only occurs on small choppy stuff, I roll big stuff with no issues.

 

I'm very curious, among others, and cannot wait to hear if this resolves this problem. Fingers crossed!

 

my spacers got rid of most of my clunk, made it happen less frequent and a lot less loud... only have 20 miles of test time though.

 

Has anyone checked their sway bar bushings where it mounts to the frame?

 

Noise persists even when not using the sway bar at all (disconnected endlinks). But, yes, I've replaced the sway bar bushings too without any change.

 

no sway bar all together

 

From what I can tell, Pipho and I both have nearly replaced everything (including removing the swaybar) to eliminate this knocking noise some of us are hearing over quick tiny bumps. The only item left to replace is essentially the LCA bushings. There is basically nothing else to replace. If the noise persist then the Titan, 08+, have serious noise issues in the front.

 

I still think it's the Radflo coilovers that we all have in common. The guys in my area with Pro comp 6" lift kits, with Pro comp coilovers are not having the same issuse. The two titans are 08 and 09pro4x.

 

Still no update from Greg? No one else has replaced bushings or LCAs yet?

 

Greg has not had time to do his own.
I have not been able to get a hold of him myself.
Pipho did speak with him and is waiting on his LCA bushing to arrive. Pipho may be the first to have them installed and will provide an update once he does.

 

I didnt say cold weather makes it worse? Ive been though my shocks 3 times this month alone and replaced upper and lower bearings, there isnt really anything in side a shock to make noise unless its internal reservoir shocks with little to no N2 allowing the IFP to clank against the top cap.

 

I didnt say cold weather makes it worse?

I think I said that. If there is a difference it's extremely subtle. Maybe I'm just grumpy because it's cold out

 

Come to think of it, maybe it wasn't Pipho that didnt say that. Who knows, not feeling well today at all.

Either way, I had my lifted Radflo's rebuilt by Glen himself and he made absolutely sure N2 was at the right pressure along with everything else.

At this point I'm just waiting.
