Hi All.

Could anyone please help me with the Part Number for the Universal Joint on the Rear Prop Shaft, (next to the Rear Diff Unit), on a 1984, 109 ,2.3 cc, Petrol, FFR.
Cant find it in the Parts Manual.

Regards.

Chris.
 
My son's series 3 petrol 2.25 LWB. at about steady 30 the vehicle seems to slightly jerk back and fore. Methinks it may be wear in't propshaft bearings. If so, does the gearbox have to be moved to remove propshafts ? If not can you give me a rough idea of how to renew the needle bearings, if that is what the problem is. Thankyou

The prop shafts are telescopic. Once one end is unbolted they can be pushed into themselves. Before you remove anything you should check this joint for vertical movement. There shouldn’t be any,
 
And if you are scrambling about underneath to remove either propshaft do some prep by lubricating the nuts and bolts at least a couple of times……….. from the side. I tried WD40 and it’s numerous cousins but eventually resorted to ‘rustola’ on the last two rear bolts that refused to shift. Also as much leverage as you can get and a tight fitting spanner.
As Bob says basic checks first though. I virtually talked myself into replacing the front propshaft as the diagnosis to a problem pointed towards it, it is very likely to have been the third thing I replaced AFTER the propshaft.

You can’t service the linear slide joint so any give in it means a new shaft. It’s simply not worth replacing UVs if this is worn. For the price of a new shaft it’s hardly worth the faff replacing them anyway. I know I quickly decided life’s too short :D

Ask him when he last greased it. If he doesn't know, the UJs are probably knackered. And the sliding joint well on it's way too.

Like Bob^^^^^^, I don't bother to repair them anymore. New ones aren't a lot of money. Grease all nipples before you fit a new one, and regularly thereafter, and you won't get further problems.

The propshaft removal tools, available for a few quid, speed up removal considerably. You have to loosen the nuts first, but after that, you can use a socket to unwind them, instead of turning the spanners hundreds of times.

I totally agree. Some people seem to be able to change uv joints easily but Ive never managed.to do it in less than an hour and without losing a couple of inches of skin and whats left of my temper.

I have one of those, somewhere :oops:

Couldn’t find it when I whipped the rear diff out. :mad: Another ruddy faff:rolleyes:
 
You guys are great. Thanks very much. Oh ! Bobstickle, my life isn't to short - at 87 I am still able to get around (slowly), pass knowledge onto my son (as well as tools nowadays (reversal of roles)) and we enjoy working together - well, he does most of the work of course. The expert knowledge and experience you all offer make repair/maintenance a lot easier. :):)

Your welcome. Always ready to have disasters so others can avoid them. Once upon a time it was the norm to change UJs but at the moment a full prop ain’t much more. Not sure for how long though.
