    Hi,

    Just wondering if anyone has had any dealings with a constant squeak coming from the rear of the car? It is there constantly when driving so I was assuming it was coming from the suspension somewhere. I guess I was just wondering if anyone has come across this before so I can get an idea before I fork out money for new shocks and springs if it isn't them.

    Someone at a swap meet mentioned to me that this was a common problem with the VH SL/E but wasn't sure what caused it. I have been unable to find any reports of this online though.

    Thanks heaps.


    P.S. The car is a VH SL/E 4.2 Trimatic, all original.

    Hadn't thought of bearings, I will check that option. Thanks.

    Hard to narrow down the squeak. It is at the back end, constant even over the smallest bump, doesn't seem to appear when standing on the towbar and jumping up and down though, can be heard clearly from standing outside the vehicle as it drives past. The Repco service agent I use couldn't narrow it down and neither could the Bridgestone tyre centre. New suspension was just the obvious suggestion from them both.

    Definitely external as it gets quieter with the windows up.

    Just though I would explore this 'common' problem scenario that the bloke at the swap meet mentioned, obviously he was wrong.

    Thanks heaps for the suggestions, much appreciated.

    does the frequency of squeaking change with vehicle speed? If so you have a rotating part issue (i.e. a bearing somewhere); if not it's a bush or something.....

    Ive had a squeak in the rear end of mine ever since i converted it to disc brakes, it could just be the pads touching the disc ever so slightly when the axles move that tiny little bit when you hit a bump, the more the bearings are worn the worse the squeak will be. Hold your foot on the brake while driving along to check.

    Thanks for the reply,

    The squeak is a constant pitch and frequency, it doesn't change with speed, etc.

    Thanks for the suggestion.

    Never heard of a panhard bar, but will check it out.

    Thanks

    Took it for a drive today and did the brake test, still the same unfortunately. But, I did do some tests and narrowed it down to the rear passenger side of the car. By going around a left hand bend at 40km/h the squeak completely disappeared but going back the other way the squeak remained. So I assume the squeak disappears when the rear passenger side when has some load removed from it.

    Something for me to work on anyway.

    What about a rear shock absorber? My brother brought his Gemi around last week and just the slightest bit of weight movement made a really loud squeak. If weight transfer around a left or right corner changes, I figured it could be that. Goodluck

    Just a late follow up, ari was spot on with his suggestion, park brake.

    When I had it back to REPCO on the hoist the guy said again nothing seemed loose, I asked him to follow the park brake and check it was all ok, at which point he noticed a loose bracket, hit it back in with his hand and I haven't had the problem since.

    Thanks again Ari.

    Glad it was sorted before you started throwing money on suspension and bushes.
