Rear noise after JBA 4 link

[jeeper03]

Just put the JBA 4 link on my jeep and since then I've had a noise that sounds an awful lot like a pinion bearing going bad. I'm not sure why it would go bad just because I added the 4 link. Anybody else running one of these and getting road noise through it possibly?? I'm lifted 4 inches with coilovers in front and JBA 4 inch springs in the rear. Thanks for any input

Absolutely sure installation was done spot on? Everything lined up?

If you don't have the below specs you will have issues.

You must be registered for see images attach

Also the pinion shaft must be directly pointed at the rear tailshaft coming out of the t-case,can not be off at all.

After the install I took it to a 4x4 shop I've taken a lot of custom stuff to before and had them do an alignment and set the angle on the drive shaft. It all looks good and right.

The 4 link will transfer more sound into the passenger compartment then the factory trilink. This is do to the 4 link not having bushings to dampen the sound.

pics of drive shaft angles and or video of said noise would help a lot here. More description of noise. Vibration? clunk ? pop? ticking? is it in relation to speed ?

It's like a whining noise. I jacked it up last night and had a friend get in and start it then put it in drive. The noise seems to be coming more from the driver side than anywhere else. I'm going to pull the axles tonight and change both bearings and fluid to see if that helps. The noise isn't to loud which Is why I don't think I ever heard it until I put in the JBA parts and it was a harder mount to the body instead of a rubber bushing.
