Ok so I cant figure this out. But my jeep starts to shake around 60mph and then goes away at 65-70mph. Its done it since Ive bought it. Ive replaced wheels, tires, axles, Ive personally balanced the tires on 3 different machines and they are good. I have no clue what else it could be. Ive rotated all of the wheels to the rear and spun them they all spin smooth but it still shakes. I know my front left U-joint is bad theres some play in it but I wouldn't think that would cause the shake so bad. Also the rear drums are original 173k on them but I also wouldn't think that would cause it either. I'm stumped. Any ideas or suggestions?

Thanks!

 

Start checking steering linkage, ball joints,hub bearings,shocks. Had it aligned?

 

Forgot to add that.. Steering linkage and shocks are new. I haven't checked hub bearings. I just recently had it aligned and the ball joints seem fine I cant get any movement out of them.

 

Whatever it is must be minimal (but could get worse) as I wouldn't think it could have been aligned. Check those bearings. Long shot but check the steering dampner(shock) that it's not sticking or just disconnect it and drive it to see if it still shakes.

 

Does it have a lift ?

 

Mine did exactly this about 6 months ago. It was the passenger side axle shafts ujoint. Might want to check them both. GL.

 

It's now driving smoother out of no where. Theres still a small shake so I'm going to change that front U-joint again and its actually like snapped lol. So I have to replace that ASAP.
