Jeep Driver Posted February 18, 2014 Share Posted February 18, 2014 I've had a rattle at the front suspension for about 6 months. Sounded like the UCA bushings were going bad so I replaced two of them, this time I got NAPA brand instead of Moog. The second one I replaced tonight since my Bilsteins came today and I was installing them anyway. BTW, what a b*@$£ that was. Anyhow, I'm installing the second shock on the front and I notice the u-joint is bad so I run to the parts store to get one, wrong size. Now I got to look at the passenger side, worse than the driver side. Completely gone, I would not have driven it again, could not believe they have not broken. I will have to wait till morning to get the two u-joints and replace both. Question is- Could the rattle I've heard have been the u-joints all this time? The ones I'm replacing are Moog and are less than 2 years old. I have replaced now just about every part on this truck twice and I have come to the conclusion the Moog SUCKS!!!!!!!!!!

Bornindesert Posted February 18, 2014 Share Posted February 18, 2014 I had a bad front passenger u-joint and it was more of a repetitive clunk when you turned it certain ways like parking at the store. This stuff can be hard to pin down. Try moving the track bar at the axle, sway bar links, maybe even the motor mount? Link to comment Share on other sites More sharing options...
Blue88Comanche Posted February 18, 2014 Share Posted February 18, 2014 When one of my front u joints went out it would clank during turns. The yoke on my front diff will rub my exhaust down pipe when I make turns or have enough suspension travel. If you changed the ride height recently the front axle may not be centered.

Incommando Posted February 18, 2014 Share Posted February 18, 2014 A common failure is the track bar mounting hole at the body side. It will rattle and eventually thunk as it gets worse. This is also a common but overlooked DW source. Link to comment Share on other sites More sharing options...
Jeep Driver Posted February 18, 2014 Author Share Posted February 18, 2014 One of my caliper bolts had snapped off at some point....>>>>>WTF? Image Not Found The u-joints were not Moog but Federals.....Precision. Image Not Found And these are only two years old. Link to comment Share on other sites More sharing options...
Strokermjcomanche Posted February 18, 2014 Share Posted February 18, 2014 Do you have bigger tires / lift on your truck ? If you are easy on the drivetrain may I suggest cv shafts they are constantly lubricated and are less prone to failure when used for light duty . Most manufactures also offer lifetime warranties on the cv shafts so you'll never have to buy another Link to comment Share on other sites More sharing options...
Comanchemodder Posted February 19, 2014 Share Posted February 19, 2014 Drove home tonight to a freakish grinding-rattling noise. The wheel bearing blew out. The only way to describe the experience of driving on spindles is "god I hope I make it home..." Anyone know where to buy 2wd spindles?

Blue88Comanche Posted February 19, 2014 Share Posted February 19, 2014 I have some v8 ZJ cv shafts on my D30. they handle much better on road in 4wd full time. Link to comment Share on other sites More sharing options...
