Hello, I just bought a 2001 Cherokee with a 3.5 " lift and a 1" TC drop.
I am getting a lot of vibration/shaking in the steering wheel. Not loose steering the steering wheel seems to shake up and down during acceleration.
I replaced a broken Castor bracket on the lower control arm and that helped but it's still pretty bad. Any suggestions would be appreciated.

 

Check wheel balance and get it aligned.

 

Many cases of vibrations in the 1997+ XJs with as little as 3 inch of lift. If it's not the alignment, look into a SYE.

 

That'd surprise me since its already got a tcase drop....

 

Whats you tcase and rear axle setup? I have 3.5" leafs and have been running a stock driveshaft and crossmember for two years, only minor vibes. I have a 231 and 8.25 rear, automatic

 

wouldn't shake the steering wheel like he described though.

Need more info, does it shake constantly? or just at a certain speed? does it start when you kit a bump/rut in the road? when was the last time you had an alignment done, and your tires/wheel balanced?? is there an adjustable track bar on your jeep? how are the bushings?

 

I'll check it out tonight, is there an easy way to identify them?

If you can put your transfer case in 4W part-time, full time, and 4LO, you have the NP242. If you only have 4 Hi and 4 LO, you have the NP231. For the rear axle, you either have the Dana 35 or Chrysler 8.25

 

I have the NP231 and the Dana 35 - the shaking is during acceleration.
an alignment is due but there is more to it than that.

 

I just finished my 3" lift 2 weeks ago. It vibrated violently after 30 mph. After the alignment, without a t-case drop, 90% of the vibes were gone.

 

I'm guessing alignment first,Some people lift and do a half way alignment in the driveway and live with it.Or if you hit something hard enough it can knock a alignment off too.

 

Sounds like a plan, I'll start with alignment and balance. Thanks for all the replies!
