Hello
I have a 1990 90 and 1997 Disco both of which have deteriorated rubber boots on the rear upper A frame ball joint. There is no play in these joints so I was hoping to just fit new boots, is this possible (either by splitting boot and using superglue or releasing the joint)?

Does anyone know if the boot is available or its dimensions? I've not had any luck googling but I can see lots on ebay if I knew the dimensions.

How realistic is this option?

theres isnt a off the shelf boot but even so replacing the joint is the answer

I have bought replacement boots for the steering ball joints, so there is a good chance you can get replacement boots for the A-frame joint.
You may need to measure the joint and see what's available on fleabay rather than something specificaly designed for a Land Rover..

Sounds like a plan. I don't fancy replacing the joint unnecessarily as it's a bit beyond my capabilities nowadays, so I'd have to pay a garage to do both vehicles. Thanks for advice.

They’ll have to break off the captive nut anyway which is the crap part of the job. Once that’s cracked it’s only two bolts and nuts and you could drop a fresh one in if you buy one with the casting already attached. Then it’s almost fit n forget.

Oh dear another decision to make now. Thought I left all that behind when I retired

Two bolts out, undo old ball joint. Easy job, if a little awkward. Just soak in WD for a few days.

You can get one here, if that is what you want to do.

This is the way to do it. I have replaced just the joint and reused the old casting but even diy it was not really worth the saving given the amount of besting with a hammer it needed. If you are paying a garage it would definitely be cheaper to get the complete u it with a new casting. Then it is just undo two bolts and the castle nut on the joint.

Also it may seem a waste disposing of your old one but once the boot is open you won’t know if any grit has gotten into the joint. At least a new one will last a long time.

definitely! It will just end up being done twice, once for the boot and once for a new joint
