Default 00 XJ vibes?

Posting for a friend who's been asking me questions over the phone.

00 XJ, he just threw 2" spacers up front and a 2.5" AAL in the rear. He said he had minor vibes, so I let him grab an X-member from a manual XJ to give a little Tcase drop. Well, apparently this made things worse, and he really has vibes now!!

Any ideas??

Also, he has clunking every time he hits the gas, or lets off.

I duno yet, haven't seen it myself, just talked to him over the phone. I think it's strange that he got bad vibes after dropping the Tcase!!

the clunking may be the exhaust on the cross member. but as far as vibes a half inch drop or so shoulda cleared it up.

isn't the front axle a LP d30? couldn't that cause the vibe and you're just thinking it's coming from the rear? cause a drop would make the already sucky front angle worse

valid. I'll look into that.

I really have to actually see it in person before I can help the kid!

I'm still voting on u-joints being bad and getting worse.

The LP D30 could be viable though too.
