I have a vibration coming from what feels the rear of my 90TC it does get worse with speed but very little vibration through the steering wheel, the wheels have been balanced as far as they can be with MT's on and the UJ's were done 500 miles ago. I have noticed the bushes on the A frame have gone and there is about 1mm play on the bearing which goes into the rear diff from the prop shaft.
Could either of these cause the vibration or would the bushes just cause the rear to wander, and how easy is it to swap the bearing that goes in to the diff?
Cheers
Mark.

Easier to change the diff, you might also have bent the prop by now. Try dropping the rear prop and drive without it.

Cheers RRB, tried that last night but still the same. :-k

I have just done my A frame bushes on my discovery as i had some kicking around and was hard up for something to do for a couple of hours,two days later the job was complete and half of the essex countryside was removed from around that area lol but mate what a difference it made it amazing what you get used to over time.My problem was simalar to yours only not as bad sometimes you could feel a wander/shake sometimes not,i suppose it could have been something to do with road surface or camber or both but its gone now and hasnt returned.if the bushes have gone as you say they need to be replaced and are only cheap,hope this helps you mate.

Then it's not the diff. Tried the same at the front yet?
-
No not yet, funny thing is it seems to only happen under load, foot down get vibration (at around 30 - 50) take foot off the gas it reduces thus why I thought it may be a bearing.
-
I can understand that.
Here's a nasty thought, a misfire. Mine does it and one day I'll replace the valves :roll:.
There are other things that can cause it though, clutches and gearbox damage, bent handbrake drums etc. Handbrake not sticking is it?
Does it keep vibrating either side of a gearchange?
-
funny you mention the handbrake, the cable has been sticking on so I changed it last week it now looks like it may have been the shoes sticking on as after it had been standing for a few day's the handbrake seized on, I have released it now and think I am going to fit an X-Brake when I have some ££££
I wonder if Simon does MC discount [-o<
-
Its usually not the shoes that stick in the dhand brake, more likely is the expander unit between the shoes. The land rover hand brake is nice and simple as drum brakes go and doesn't take long to clean up.
-
sounds like youve got a number of sins adding up to one thing i would change you bushes and do your a frame as it is these that conect everything at the back end get wear in both and and replace one the othere still shakes and so on
-
i have a simular problem i have changed just about everything i could think of it got better but didnt go away then i notices it only happened in 4th gear :shocked:
-
MIne does it in %th only, but I think it's an engine misfire. The power/torque changes with different gears which makes itharder to elliminate.
-
Another thing to try is to swap out the prop shaft, my dad's old van used to do it and that was down to propshaft and UJ wear.
