Hi all. Had a really bad vibration from the back of the Disco the other day so ordered a replacement rubber coupling...

Now I seem to have an uneven gap at the rubber coupling end when I try to refit the prop shaft. I've tried changing the position of the propshaft at the handbrake end but can't seem to work out why I can't get the two sides to marry up?
Don't know if the pic actually helps any.

Any ideas?
 
Yes, but is the gap still the same when the car's on the ground? Depending what position the front of the car relative to the rear axle was when you fitted it will give varying degrees of gaps.
 
rubber coupling will be slightly distorted when its fitted , its rubber to allow for some angular movement between prop and axle, its usual to only notice it when you refit a new one
 
The car is not off the ground, I drove up on a ramp to give me room ti get underneath.

How much difference in the gap either side is acceptable? Seems quite a way out to me... When I compare it when looking under my other Disco (same year) it seems more even - maybe it's me...

Any tricks to getting the old seal (supplied with the new rubber cush) out from the rear diff end?
 
if its not in bad nick leave it in and just replace coupling, i use a slide hammer and blind hole bearing puller
 
Sharp cold chisel, prop in vice and belt hell out of bush until it folds in. Its a swine without a slide hammer which I dont have. Some suggest hydraulic pressure using grease packed in hole and hammering a flush fitting rod in. Didnt work for me!
 
Bashing it sounds like the way forward... :)

I still don't understand why there is such a discrepancy in the two sides lining up - it has to be close to 5mm.
If there is a 'Hardy Spicer' option, as on the 200, why change to a rubber cush?

Weird.
 
As you can see, my rubber had split.

However,mreplacing it with a new one hasn't solved the problem? I still get heavy vibration at around 30 mph under load - no vibration when I take it out of gear?.

Any ideas?

They made the wrong choice when the changed to the rubber doughnut in my opinion. Id source a 200 tdi rear prop and 4 bolt flange and seal then change it. Better in the long run.

But then the later V8 D1s don't have such a thing.
 
V8s have to much grunt theyd shred them in no time. Id rathet change a uj on a prop than a doughnut so 200 or v8 prop all the way
 
My 3.5 V8 had one and in the 10 years of ownership and 100k miles it never gave a problem.
Also the doughnut returned on the V8 D2s and without any issues so that "to much grunt" theory is blown out of the water. :D

It seems to me it's just a 300 tdi thing. :(
 
Ha, ha,ha...:) Thanks James - didn't know there was a spacer option. I Thought the sliding prop would have sorted that out?

spacer goes on the pinion before the flange ,previous to the 3 bolt flange all diffs used a spacer ,3 bolt flange had spacer built on , and so do some later 4 bolt flanges, its nothing to do with the prop
