My truck runs fine, it only has 13K miles. But when I put it into 4 wheel drive the front end shakes when I get up to about 10 mph. I have a 6" Fabtech lift kit with 37" toyo mt open coutry tires. What can I do to fix this?

what shakes? the whole front end or what? does it go away after 10mphs?

mtrueblood

The whole front end shakes and I haven't gone much over 25 with it in 4 wheel drive, but no it doesn't stop shaking

something is wrong obviously, did one of the weights got knocked off the driveshaft? is the driveshaft loose? is donesn't do it in 2wd correct?

mtrueblood

No it doesn't do it when its just in 2wd.

i would check your driveshaft 1st, just the easiest thing to rule out. did you install your won lift? if the driveshaft is OK, i would guess the front diff is loose and is vibrating, if not that, i would check every nut and bolt on the whole lift, something that to be loose.

Check and make sure they tightened up the CV bolts! Actually check all the bolts, with a 6" lift lots of new bolt were put n.

how old is your lift? did all the bolts get retorqued 500 miles later?

its most likely that you didnt make the notch in the drive shaft? i had to my manual stated if i felt the vehicle shaking in 4 wheel drive that would be the problem. thats what i am guess. i needed a grine just to make a notch and it worked perfect. reread ur manual.

i just read the install sheet, did you have the front driveshaft rebalanced?
