Hello everyone, i just got my first jeep. Its a 95 yj with a 4" lift. From what i have researched it seems to be a rough country brand and everything seems to be installed correctly. Right now it has bfg's 30x9.50 and all stock axles. When I get around 55 mph I get a vibration. What recommendations do you guys have about getting rid of it?

Thanks
 
Sell it and buy mine!


No really have you had it aligned or had the tires balanced?

is it a driveline vibe or more of a shimmy in the front end/rear?

I mean you could be talking about driveline vibes, out of balance tires, needing an alignment.


More details por favor
 
What Renegade said. It should have a T-case drop if it is a 4" lift. If it has a drop, then look at the u-joints next.
 
i believe it is in the drive line, you can knock it out of gear and the vibration goes away (while still traveling 55)

the t case has the drop in it that comes with the kit, are you saying drop it an additional inch?

as far as rotating the rear axle up, is the wedge block attached to the new springs not at the correct angle?


thanks for your input

Sounds about like it should. Have you checked the rear driveshaft U-joints? check for play up/down and left/right.
 
Do you have a tcase drop?
