Clunk on Range Rover

Thinking caps on please!

I am getting a clunk from the rear of my 89 RR. Sounds a bit like knocking two hammers together, and can be felt through the body when it happens. Will do it when going from side to side on twisty roads, also hard acceleration, followed by HEAVY braking can reproduce it. Work so far... Have fitted complete poly bush kit, including the top bushes for the a frame. New ball joint. New springs and shocks all round Replaced panhard rod bushes at the front as they were knocked out by a knackered steering damper.

Any idea welcomed

You seem to have pretty much covered the standard stuff! Propshaft is sliding OK and the rest of the drivetrain is in one piece?

I've seen this on the 110 - there's also a thing about 5/8" bolts versus

16mm bolts. on mine, it had various loose bolts, and they were 5/8" UNF. got some to replace 'em, 16mm metric, and high tensile to boot... The problem with bolt length is not so much of a problem provided they're done up tight.

If the holes are worn, you want a large thick washer (at least 3mm, you may have to make this or get it made) with the right size hole (16mm), assemble, tighten bolt, tack weld it to the outside of the plate with the original hole, take it apart again (or you'll melt the bush) and seam weld around the washer, then use a longer bolt.

I think that the damage with mine started with the previous owner. It would have been nice though if LandRover had designed the bushes and mountings around a particular size bolt, rather than the bolt looking like it was an afterthought.

All four of my lower shock mounting points need that treatment as well.

Exactly what we found on neighbours 110. Pretty scary really when you consider how oval the hole was by the time we found it. But 5 mins cleaning with the floppy grinder and another 5 with the MIG and a large washer had it restored.

Took 20 mins to find the washer though :)

Ta for the thoughts guys. I had the work done while I was away, and only actually changed the rear shock myself, so I can vouch for them, but that is about it. At least all the bolts are new, with plenty of copperslip, so they should all come out easy enough. To be honest, I don't think this is going to be the problem, but I have to eliminate it. The guy who did the job, is an absolute perfectionist, and I don't think something like that would get past him, but who knows?

Perhaps the best way to describe the noise would be to refer to the clunk that you get on series motors in the wet when the spring bushes are shot - more of a clack than a clunk!

It can also be provoked driving diagonally through ditches, which was where it was first noted. The fact that heavy braking and acceleration could produce the noise came as a surprise.

Ah well back to the garage...

sounds like shot bushings.

Take care Pantelis

... and when you find it tell me. Certain leaning, certain speed, certain day of the week and phase on the moon and mine 'clanks'. Sounds almost like a rear spring reseating after dislocating ... just can't be at the time. Again, my motor has just been rebuilt so most things are new or known good ... except for something ... somewhere ... :-(

I assume you've got a load leveller? Is it working and are the joints good? (Not my problem as mine has been removed).

Have already been at the load leveller with a gas axe, so it aint that! Going to try disconnecting the shocks and getting someone to rock it heavily from side to side to see if I can provoke the noise while on the driveway. Doesn't do it with the shocks connected, but can't really rock it that fast.

Will keep you posted as to what I find. Thought I had seen a crack on the lower spring support, but was only the paint. They are looking a bit thin though, so have filed those away for renewal - probably when they snap off!

All thoughts so far much appreciated. Bushes are less than a year old ( poly bush) but it was doing it with the old standard bushes, and continued to do it as soon as the new poly bush was fitted. Must be something I haven't looked at yet - just can't think what.
