Squeaking D4

[mijango]

After some mud action on the weekend I gave my D4 a wash underneath with a gerni (high pressure water jet). Maybe stupidly so :-(

I took it for a drive just now and there is an unhealthy squeaking from the wheels a only the front but possibly the rear too).

I'm pretty sure it's not the brakes/discs as braking doesn't change the noise and it continued when I slipped into neutral so at least it's not engine related.

Any ideas what it is and what precautionary measures I should take??

Sounds like you've jammed a stone in somewhere.

Awful squealing from brakes can be caused by stones trapped, try reversing the car for a bit, then driving forward. Worked for me on a recent outing.

Thanks guys though I don't think it is stones as it's coming from several wheels and only started after I'd used the gerni.

I always wash everything, both under and over, with a high pressure water jet with no problems. You must have washed some grit into the brake pads or even between the wheels and the calipers. Even after driving on the beach I have had serious squeals from trapped sand or small stones, which is a bit disconcerting when it happens.


Driving along the Binns track in the NT last year, we stopped at one point to lower the pressures on my son in law's Patrol (it was too rough for him in the Patrol) and saw a whole lot of aluminium swarf on my left rear wheel. The GOE wheel had a stone jammed between the rear caliper and the rim and the rim was being nicely machined where the spokes join the rim! Reversing dislodged it but it caused me a fair bit of consternation until I found where all the aluminium filings had come from when we were half way between Alice Springs and Darwin on a little used track.

Can sometimes get things enter and be jammed within the hand brake drums. You have to remove the drum and clean it out to get rid of them. They won't fall out or be dislodged by reversing in this case.

Well - problem solved. I called up Coopers on princes highway (Sydney) where I recently had it serviced and they suggested spraying silicon on the anti sway bar bushes as there could have been some mud/grit washed in to them. After a short drive (and a bit of 'swaying' :-) I'm back to permagrin!!

Hi mijango,
I guess that you mean Graeme Coopers in St Peters (Sydney). A great coy. servicing LRs for years.

Best Wishes,
