Top Balljoint ....Help/Advice

Has anybody here ever changed the rubber gator on the front suspension top balljoint? I accidentally split mine a tiny bit when I split the joint to set the camber. At the time I didn't realise there was a special tool for splitting the top joints but I do now!!

Anyhow, I thought, no problem, I'll get a replacement rubber gator, pop it apart, stick the new one on an all will be well. It's a nightmare because the gator has a metal edge which is an interference fit onto the rebate in the casting around the balljoint. My digital calipers tell me that the ring on the gator is about 0.75mm small diameter than the casting. Having ruined two new gators trying various ways to get it on I thought I'd cry for help on here..... I've tried pressing it on, even made a special wooden press shape to push on the bevelled edge, all to no avail. Tried, freezing the ball joint and sticking the gator on boiling water. and if it were not for the fact that I don't really want to go and get the camber setup again, perhaps I'd be better to just order a new ball joint as a complete unit.

Anyhow, that is quite a rant! Sorry.......anyone got any thoughts?

Graham,

I nicked one of mine using two pairs of water pump pliers.

For the other side I used a hole saw / bit of ply to make a 'rest' for the metal collar and put it in the 1/2t bush press. (Took the ball joint off the wishbone after measuring its position)

Thanks Ian, I've tried something quite similar but not with a holesaw. I'll see if I can find a pipe of the right diameter and do as you did. I had a go with a socket that I thought was a good fit but I reckon it bent the new one slightly out of round and it was game over from then on.

I use a suitably sized round piece of pipe and push it in using a vice. The only satisfactory way I've found.

I thought 2020 was the year that was going to give me all I wanted. It turned out to be the year to make me appreciate what I've got.

Same as paul  but a large socket and vice, same result.

I know it`s too late but.......my MOT man said that as long as the split was sealed it would be ok and to use any black sealant (silicone etc.) They do tend to split/fret quite easily.

Same issue here.  I put two new gators on, ended up having to grind out the inside if the metal collar on the gators with a dremmel until it fitterd.  A real pain!

Regards,

Stuart

It's only £30 for the ball joint from Caterham, save the bother and just buy a new one!

I found the centre tube in an axle stand was the ideal diameter to hammer the steel ring in place without damaging the rubber. Having also damaged a new one trying other methods.

For best results I'd avoid using a hammer if possible. Using a vice allows you to gradually squeeze the gator on and ensure it goes on square.
