Hey everyone, I just bought a 2010 Titan 2wd with 20" rims and Toyo Open Countrys 305/55/20 and the truck has a lift kit on it already (6" I believe) and the truck only has 8k miles, Anyway what I was wondering is when I brake, sometimes not all the time it feels really rough kinda like theres a sub woofer under my seat is the best way to describe it. Any ideas on what this is? or if it's normal?.

Warped rotors possibly? I'd say for sure your transmission mount, but since it does this only on breaking and not on accelerating than idk.

I havent noticed it on acceleration, but I may not just be paying attention. hmm not sure about the rotors ill have to check them tomorrow. (how would I tell if they are warped? I know probably a dumb question)

i dont know if just by looking you can tell they are warped. maybe feel them all around?? Not too sure. I know my rotors got warped really bad on my 06 with the lift and 35's. A shop could check them. Since you feel it from your seat and not the steering wheel it makes me think its from the rear rotors. But I could be totally wrong. I'm sure someone will chime in with much more knowledge.

u check all the bolts on the lift itself? bracket lifts have what are called kicker bars and they come off the back drop down bracket and attach back up to the frame allmost at cab location maybe the lift itself is lose and when you break everything is flexing back towards the rear under force? shot in the dark but what your describing could literally be anything...have you driven with a lift before? give us a little more background on the prob

No this is my first truck with a lift, thats why I was wondering if this was normal when having a lift and bigger tires. And I've only had the truck for 3 days so I don't have much of a background I just notice it every once and while.

i have a 2010 as well and noticed this slightly rough feeling while breaking too and my rotors are not warped. i only feel it though for the first couple miles after i havent drove it for a little while. i feel it a lot in the pedal and floorboard. to me it almost feels a little like the transmission or torque converter but its hard to tell...i only feel it while breaking. shes done it since new. warm or cold outside...doesnt matter. ive also checked the transmission mount and its good. weird

My steering wheel doesn't wobble either, So I'm going to check a few things that were mentioned before and then I guess not worry about it until something bad happens so I know for sure what it is. Thanks for all the info!

*Update* Ok so I was driving today and I noticed it's not actually when I brake it happens during down shifting and It seems to be either in 3rd or 2nd gear that it happens and then once it down shifts to a lower gear it stops.

It sounds like you're picking up a vibration from the rear differential. I had a truck with a 4" lift in it, and when I decelerated or let off the gas, the differential would 'snap' back into place. I tried several different things to fix it. In the end, a number of other people told me this was the case, and the only way to fix it was to re-angle or (shim) the rear diff. so the drive shaft angle remained constant.
It you're experiencing this while braking, and you feel a vibration through the seat. Then most likely it the rear rotors starting to 'warp'.
Most of the time, when your steering wheel shakes, and the brake pedal 'pulses' while applying the brakes. It's the front brakes starting to, or have gone bad. Turning the rotors is ONLY a temporary fix. It will usually reoccur after a few hundred to a few thousand miles.
Keep in mind, that running oversize tires, will also increase the amount of rotating mass. It's added weight that the brake system has to deal with in order to stop the vehicle. This WILL add more heat and put additional stress on the rotors and pads. An inferior or sub-standard pad is not able to handle the heat and will FADE. The additional heat is then transferred directly into the rotors, which will 'warp' or start to heat crack.
Hope this helps.
