I bought my 2000 TJ 2.5l manual about 6 months ago (112k miles). I'm almost positive it was lifted from the precious owner, sitting on 31's though. Whenever I got above 45 mph it would start to vibrate. Last week I had the tires re balanced and rotated, which did not really fix anything.
A couple days ago I was changing my t-case fluid and noticed there is quite a bit of play in my front drive shaft. Rear shaft felt good though. Now, I am thinking all my u joints need replacing.
Would this be the next logical step to get rid of my vibes? I notice it more in my seat than in my steering wheel.
Any guidance is greatly appreciated.
