On compression or rebound? I have the Procomp 6" Stage one 2 weeks old

 

check the area between the transmission/transfer and body/frame, there is a rubber mount w/ spring that "secures" the transmission/tranfer to the truck. I noticed mine had torn all the way around the rubber boot, which allows a lot of movement when I drove it. It made a God-awful thump, when I got on it from a stop. I don't know if this is the cause for your thumps, but worth a try...

 

Mine makes an aweful thud when I go over a bump and both front tires drop at the same time. I only have a leveling kit and there are marks on the coild bakets, but they have never gotten worse. It did it before the kit anyway. If only one tire hits the bump it is fine. If both drop, it sounds like my dash is about to fall off it is so loud!!

 

That is the exact reason I went with a full suspention lift on my 07, I had too many issues on my 04 with this same problem. time for some new arms i suppose or spindles?

 

Thanks for the info guys. I'm still driving it, and its make me insane. The shop that did the lift kit say that nothing is loose or dangerous. I took it off road, and hit some pretty serious bumps. I notice when I hit a bump that makes the suspension really work, I don't hear the noise. But only small bumps seem to do it...any thoughts?

a friend of my dads wants to drive my truck, to decide if he should lift his titan, or level it. I really would like to explain the noise to him, and the shop too!

Thanks!

I love this site!

 

You never said if it was the Stage 1 or Stage 2 Fabtech. The stock C/O's are junk and probably what is making the noise. Or else the rubber mount that DRTYAZN mentioned.

 

I've got the same thud/thump on small bumps and sometimes just when turning? I have the PC stage 1. its pretty annoying! I hope its just the crappy coilovers as 54 says.

Same here...it drives me nuts...I have benn under my truck seems like hundreds of times looking for loose bolts.....if both tires drop at the same time its quite, but going down a bumpy road when the wheels move independantly then i can hear it, and feel it in the floor board. Very annoying. Please post if you discover the issue.

 

When i bought my truck I had a small thump coming from under my drivers side floorboard and it turned out to be my Nerf bars! The front bolt had managed to back out a little and it was loose. Maybe this is the problem?

 

It is also possible that the OEM shocks are worn out or too short for the lift.

 

I don't know the difference between the Fabtech and ProComp, but I have the PC stage 1, stock coils and shocks... I have no thuds once the transmission/transfer mount got replaced, however from what I gather from what is being described here could simply be the nasty tire rub or bumpstop hitting. If this is the case, you are definitely going to have to get some new coilovers, let us know when you find out what that "thud" is when you track it down...

 

Would it be the bumpstops if it only does it on small bumps? My truck wont make this noise if i'm hitting a large bump, with both tires at the same time. Only when I hit small ones in the road, with one tire at a time does it do this. It's freaking driving me up the wall. I work night shift, and sometimes coming home in the morning, dead tired, listening to that is enough to really piss me off.

I'm calling the truck doctor back next week, I really hope they can figure it out :grimrippe

 

Please pass on the info if you figure it out....I was under my truck again yesterday and found nothing....mine does it only when small bumps are hit with one tire at a time....i feel it on the drivers floor board.....if I hit a big bump it sounds normall....i wonder could the brake pads in the calipers do this......if there not tight fitted?

GOD STOP THE MADNESS,,,,lol

 

Rgregory,


That is EXACTLY what my truck does...and it's driving me INSANE!

Anyone else have this problem??

 

Just got a call from Schwabs. They are thinking it's my struts. Is this possible given the fact I have have 30,000 miles on those struts??

 

Try pushing down on your front bumper at each corner. If you feel the truck rebound, then stop quickly, then it is probably your struts. They are not providing any dampening, and they hit their extended limit. When they hit the limit, you will feel it inside. You can also feel it when bouncing the front bumper. Good luck.

 

Yes, the front struts can be worn out in 30k miles or less.

I have the exact same issue and sound....My truck has only 8000 miles.....I would hope they wouldnt go out that soon.

 

I crawled under the truck today....When you push up on the truck from underneath you can hear a "clunk" on the up and down. You can also feel it when your pushing on it. I'm hoping it's the struts, because i'm about to bite the bullet and buy some new ones. Do you guys think thats what it is?

 

And another comment. Would the struts be bottoming out on rebound when they go bad??

 

Mine does the exact same thing, I only have a leveling kit which would not interfere with the strut lenth or travel, and I only have 8000 mile on my truck. I tore the whole front end apart this morn and re-installed and re-torqued everything, and when I tokk it out on the road to my surprise the thud is still there. I have a 2 wheel drive so there is not a transfer case to worry about....it has to be someting that a 2wd and a 4 wd drive have with common parts. I dont know what to do at this point........

 

If you truck is lifted you could be topping out the travel of the shock in the strut. A leveling kit wouldn't be going past the limit, but the internal bumper on the shock can certainly get work down with use.

I just had a 4in lift on my Titan, and I had Schwab's put RS9000X shocks on it. They work great, and only made a clunk noise when I had one maxed out on the rebound. I set them all to 4 for street driving. I max them out for off-roading.

 

Im sure the shock isnt getting maxed out....were talking small bumps like cracks in the road and when i hit big bumps there is no clunk.....its only clunking on the small quick bumps.....street cracks or things like that......weird and SO DARN ANNOYING.

 

Mine does the clunk on small bumps too. If I had to guess, I would guess it's the strut. I'm going to have my two from struts replaced. I really really hope thats fixes the problem!:crybaby:

 

Have you jacked the front off the ground, by the frame so the front wheels are off the ground with the strut at max extension, and checked for freeplay in everything?
