I am having a major vibration issue that i need a little help with. I am capable of basic repairs and diagnosis but this one beats the heck out of me.

i just recently put on new front hubs and new bearings and seals and fluid in the rear because i was getting vibration while driving. a lot of the vibration went away. it was mostly in the front and i did the front hubs and figured i might as well do the back bearings while at it. i also did rotate the tires, i am in need of an alignment so the tires that are in the back or unevenly worn.

but now my issues is once i hit 50 mph i can feel a strong vibration throughout the car, it does become less noticeable when i set the cruise control at about 65-70. i am wondering if its just because my tires are unevenly worn in the back or if its a bad u-joint or what.

i did check the back u-joint for play before doing the bearings and it didn't have any play. and i apologize if this is a bit long but i figured the more information i give the easier it will be to help diagnose the problem.
and thank you for your help.

 

It is at stock ride height or lowered/raised? (Pinion angle)

Also, bad belt in a tire, BJs, lots-o-things can be causing it.

Sounds like a classic U-joint. Also check your CV Half Shafts.

 

@IndyDurango its stock suspension

@hydrashocker its 2wd. no cv halfshafts.

how hard is it to replace the u joints if they are going bad?

 

Just take off the driveline and take it to a good shop like http://www.sixstates.com/products/products.jsp and have them replace em for ya.


Really they are not hard to install and all you need is a vise and Google it!
