Thread: Cracked Coupling Prop Shaft

If we are talking about the rubber donut - seems about rite. Mine went at 100,000 km with road use - they are cheap to buy and easy to replace.

Some people replace with a unversal joint (different shaft required) but others stick by the donut as it does help a little to cushion drive line shocks - I do think they should be been listed as a service item for the 100,000k service though.

Reckon you were lucky to get to 110,000. Mine went at 50 something thousand. Mostly farm work though - quite a lot of low range stuff.

I did 3 in 30,000kms...

Changed to UniJoint and never looked back for the next 80,000kms.

You can get unijoints anywhere, donuts arent as easy to find!

Mine's done nearly 160k 8O .... starting to crack around the bolts

They're about $120ea to replace. Just change them. IF you go to a uni type shafts its then about $70-100 for the 4 bolt pinion flange and about $300 for the tailshaft. Unless you get gnarly with it in the bush, the donuts will last though.

This one was about 6 month old before I landed it wit a bit too much noise pedal. ops:

Slunny. Could you tell me what the bracket does that is bolted to the underside of the diff. housing? (on the pic)
Many thanks sheff.

Harmonic Damper, standard on the rear diffs of Series 2 Discovery.

Series 1 doesnt have one at the rear but does have one on the front diff.

Slunnie,

The dead coupling in the pic was it a GKN brand, there are some cheap and nasty ones on the market which do not last. I could not see any markings on the one in the pic.
