Thread: bump 'thump' from underneath and lubing...

I'd had this thump when going over bumps for while and had looked at suspension mounts and followed a few tips from other posters with noises.

while I had grumble up the stands for my pre embarkation checks last week.....I put a spanner over every nut and bolt I can see......I found the rear damper (shocker) mounts able to be tightened about 1/2 turn and dutifully did them all.

while I was under I went to grease uni joints etc , but my good grease gun wouldnt pump.

tried everything to bleed it , but no.

pulled it down and found the grease had hardened.....the emulsifier I guess that's what it's called had bled out and left a very heavy paste that the gun wouldn't pump.

cleaned out the plastic tube and refilled it with some very good quality grease from a can and finished the job.

the gun had only been sitting since August last year.

any way, the road test following everything was very pleasant and bump thump has disappeared.

so if you have any thumping over bumps check your damper mounts.

Den.

Agree. When I recently changed my axle to trailing arm bushes, I found the bottom shock mounts loose or not as tight as they should be.

The clunk when going over the gutter on an angle in my driveway seems to be gone.
