so I have an 07 titan 4x4 with a pro comp stage 1 6in lift .. I recently added bilstein 5100 on the middle perch with 35/12.50/20 . After this though I've noticed this real bad shake from the rear end where it almost shakes me out of my seat . The kicker is though with weight in the bed of the truck it doesn't do it hardly at all but when it does happen it's between 45-60 mph any help would be appreciated .
Yea had the tires re balanced and the alignment done . The thing really confuses me is that it goes away if I add weight to the bed of the truck lol I'm ready to sell this thing it's driving me crazy.
Are the rear shocks too short? Shock bushings worn out?
I would have said inspect all u-joints, but the symptoms going away with a load in the bed dismisses that....I'd check them anyway.
Changes with load could be from changes in driveshaft angle. Some trucks require shims to rotate the rear axle slightly to prevent u-joint chatter. Also trucks with 4" or more rear lift should have the PRG drive-shaft spacer.
Ive been running a lift for almost 10 yrs now with no drive shaft spacer. I guess ive been lucky.
May be a shot in the dark but, dont forget to check out the shackles and leaf springs.
Also, once you get this figured out I highly recommend the parts canadian listed above but, also some traction bars. For the money, they were the most noticeable difference in all around stability of the truck.
i actually already have traction bars they definitely are nice. but im thinking about taking out the 3in block in the rear and switching to a 2 to see if that changes anything I figure after that ill know forsure its something to do with driveshaft angle. either that or its something shaking up front that just shakes so bad that I think its the rear... who knows anymore.
The first thing I would do is to over every nut and bolt with a torque wrench. This reminds me of when I bought new shocks for the truck I had before the T, a 97 Dodge Ram 1500. I had a new set of shocks installed, but had some shake from the rear along with some noise. It turns out the shocks were only finger tight. The tech forgot to tighten the bolts. When I used to autocross or run time trials, I always spend time going over the entire car with the torque wrench. Bolts and lug nuts don't always stay tight.
