Hi Guys,

First post so I guess I should introduce myself. My name is Luke, I'm 23, I live in Australia. I have grown up around Jeeps thanks to my Father. My current Jeep is my first 4x4. Its a 2007 Commander Sport (Navigator pack) with the 3.0 CRD and QD2. Currently has 134000km on it. I purchased it about 8 months ago from a car yard. Has full service history at dealer, 1 owner etc. Absolutely bone stock. I have fitted a UHF, GDE tune, LED light bar to factory nudge bar, catch can, diesel pre filter, lift kit.

When all is going well I absolutely love it however I've had my fair share of issues. Everything from glow plugs to a replacement turbocharger. Most of which was covered under used car warranty.

Ok on to the current problem:

The front struts are rubbing against the body/fender where they poke through the body, under the fuse box and coolant tank. The thread of the strut above the main nut is hard up again the steel fender. When driving this creates a horrible squeek/rattle that drives me crazy.Happens on both sides.

This started happening after Dad and I fitted a 40mm Dobinson lift kit which consisted of new springs and shocks. Dobinson is an Australian owned company. My father has used there lift kits many times with no issues. I have double checked the part numbers, reassembled the struts, loosened and re torqued all relevant bolts with car on the ground. When I jack the car up off the ground some of the pressure seems to come off the fender. Right hand side is pressed up against the rear of the hole in fender, left side is pressed again front of hole in fender.

The only thing I can think of is the top strut mounts are warn/failing. I have ordered replacements but they are going to take about 3 weeks to get here and I'm not confident they will fix my problem. Local Jeep specialist who sells Jeep only parts/accesories says he has never fitted or needed to replace top strut mounts in a commander or 2006 on wards Grand Cherokee. As far as I'm aware there is no difference in the left and right strut. Any ideas or things I can try?

Thank you, Luke

No sorry, will try and get some next time I have it apart. I've only heard of one other person with the same issue and it was due to a 'busted eibach spring'. They didn't specify exactly what was wrong with it. My springs appear fine and are seated in the insulators fine.

So the dobinson lift appears to be similar to an OME lift, although less height is gained.

I know that when I replaced my struts I didn't tighten down one of them enough and it rattled pretty bad. Are you sure that the assembly was installed correctly?

Is the upper spring mount rubbing?



Or the nut on top of the strut is rubbing something? This is what I had a problem with. It has to be VERY tight.



Ok i reread your original post. It sounds like the nut is rubbing on the hole in the where the strut bolt sticks through. I'd just clearance that Hole. I had to open it up to tighten down the nut on the strut without completely disassembling the suspension again. Hit it with some paint to protect the metal afterwards. No problems.

This is where your rubbing right? (top arrow)




Some small cuts in the sheetmetal (dremel worked for me) and some work with a hammer should get you this



That nut should be recessed however so, unless the nut is larger than stock it shouldnt be rubbing there...

You guys are spot on. Its the thread above the nut that is rubbing on the hole in the fender (I am also running 1/4' levelling spacers). Was trying to avoid cutting a larger hole but that may be the next option. The nut is as tight as I can get it with the strut in a vice and a long spanner. Unless it is loosening off when driven.

I thought if the bearing or bush in the top strut mount was worn it may allow side to side movement of the strut shaft, causing my problem. Anyway ill keep you posted. Thanks for your help.

Gotcha. Happy I could help a little. Maybe wear in the bushing is causing that? If that doesn't fix it I'd go the cut and pound method. Pretty easy to do. No issues structurally.

I was just doing some research on clunking with an OME lift and I'm going to give this a shot. I'm at the point where I've tightened every bolt down within reach, replaced all ball joints and bushings (except for LCA), and replaced my sway bar end links and I'm still getting a clunk with small bumps. It's driving me crazy!

My problem is that I don't own a Dremel tool. I've read one post where someone actually pounded the hole with a socket to enlarge it. Seems like it would take quite a bit of pounding to get to widen. I'm wondering for this situation if I can get away with just pounding it with a socket too or is it much quicker with a Dremel tool that it would be worth the investment. I'm not sure how often I'd use it though. I'm going to take a peek at how many threads are exposed first and go from there.
