Had the OME lift installed yesterday. Drive home from installer all was good. Drive into work this AM was good too, until I got to the parking garage and went over those stupid speed bumps (3 in a row). There was a definite clunk on the passenger side. I took them all at very slow speed, as I always do. Same thing on the way back out tonite.

Did a quick inspection when I got home, and the first thing I noticed is the the bump stops were halfway down the strut shaft on both sides. Is it possible that that is the cause, or at least part of it?

When I initially heard the cluck I figured it would be due to the the top nut on the strut not being tightened down enough. Maybe both are the issue?

I pressed the bump stops back in as far as I could. Is there anything that can be done to make sure they stay put?

I'm going to take back to the installer tomorrow, but any thoughts or opinions would be appreciated.

EDIIT: one more question - the instructions online say there should be 3-4 threads exposed at the top of the strut nut, but the searching I've done on here some have gotten 7 to 11. Safe to say 3-4 isn't enough?

Loose compression stops have been known to cause clunking noises. To help keep them in place I put a few dabs of RTV on them before wedging them in place.

The instructions for the OME are a bit misleading. If you don't tighten the nut down until it's bottomed out you'll also get a clunk. Members who have had this issue have drilled larger holes above the strut so they could tighten that nut without removing the whole assembly from the vehicle again.

No I stayed with the stockers because the joints were still good (and to save some $$$). I'll eventually upgrade those when the stock ball joints are done.

I'll definitely take another look, but from what I remember the angle of the upper arm was such that it would take some serious compression the have them contact.

Thanks Matt. Since I was getting the clunk on just the passenger side and both of the bump stops were down, I was guessing that maybe they weren't the issue. Otherwise wouldn't both sides would be clunking? Good idea with the RTV. Any thought on the best way to press them up snug?

I was just reading a thread about reaming out that hole to gain access to that nut from the top.

A properly placed pry bar, using the spring as a pivot point, is more than sufficient to wedge the compression stops in place.

I'd do that first... its easy enough. If the clunk is still there, take a look at tightening the strut mount nut.

Don't rule out sway bar links either. If they're aged, added lift has been known to cause the links to start clunking. In most cases they were on their way out regardless and the lift just finished them off.

Yeah, the sway bar bushings are on the to do list for sure. I can tell from feel though and where the clunk is coming from it's high up on the right side so it gotta be either the bump stop or the nut not tightened down fully.

I had pried the bump stops up with a long screw driver wedged on each side. Good idea with the pry bar :)

4-5 threads showing isn't enough if you ask me. I've installed 4 OME lift kits so far between my XK and three friends XK's. I tightened that nut to 7-9 threads showing and not one issue what so ever and no clunks
