back end noise

[deff1]

g'day can anyone help i have a loud thump coming from the back of my 98 110 when the rear wheels drop into a hole or even just off the gutter. I have replaced trailing arm bushes top and bottom, A frame ball joint and bushes, new shocks and coils. It sounds like the body hitting chassie but have looked at that and there are a couple of mounts on each side that are not bolted but no rub or wear marks to show they are hitting. im pretty much out of ideas:(

Some times I get a strange noise around the back end, it has nothing to do with cars though:p.

Check exhaust system bushes, the exhaust could be hitting.

...Try unplugging the subwoofer then..:p

Seriously it sounds as if the shocks are 'topping' out, they may be too short for the coils. What springs and shocks did you fit?

checked the exhaust, wasn't it and no subwoofers in my fender:D shocks and coils both old man emu. dont think they are bottoming out as the thud happens on a small step like a gutter. Cheers for the replys

Have you got any gear inside the vehicle thats not held down securely. Perhaps something like a bottle jack rocking sideways as one wheel drops?
Or spare wheel carrier?

Does it have a sway bar fitted to the rear!
Might be worth checking the rubbers if it has one.

Check that the bolts holding the tub to back x-member are not loose. Also check rear door for a cracked frame, especially if it has a spare mounted on it, although this is usually a rattle not a thump. Another possibility, although it usually has other symptoms, is either a loose wheel bearing or a loose wheel.

gday i recon i have the same noise my 110 seems to land very heavy, i came from owning a couple of leaf spring cruisers and after having a good look while wandering around under the rover with a pry bar sorta decided that it all seems to be in good nic, so will be very interested in finding out what others have to say

Definetly sounds like shocks topping out, my old d2 did this really bad until i got longer shocks..

I think so to, OME shocks are not that long in the stroke and don't take much to top out even with standard springs.

cheers blokes have looked at all said now, no sway bar on rear, no gear moving around, mine has been cut into a ute with drop down tail gate so its not rear door. if its shocks i should be able to flex it up and see how far they go down in stroke and work out wether thats it shouldent i ?:confused:

Suggestion - if you jack up the back by the chassis on stands so the wheels are clear of the ground, and then jack up one wheel by the axle; if the jack is suddenly released you should be able to produce the noise and track it down.

Yes, you could measure it without much trouble.
