Cool Rubber boots

Can anyone tell me the size of the rubber boots on the coffin wishbones. I have both sides damaged and would like to replace them before all the grease comes out and they start to wear. No play at the moment, so I need to get them done soon. 2002 Boxster S.

Do you think you can find replacement ball joint boots and install them onto your old lateral suspension arms? I seem to recall they were crimped on to the lateral suspension arms, as an integrated assembly. Never heard of someone replacing just the boots on this particular assembly.

I managed to successfully remove the upper circlips from my ball joint boots, and while squeezing the boot to open up an opening below, managing to dab in fresh grease into the balljoint using a toothpick to keep the balljoints well lubricated. Rotated them 90 degrees also so they wear in different area. Getting the circlips back on was the trickiest part. Did same treatment to the tie rod ends when rebuilding my '01 Boxster's suspension that had 110k miles on it. Luckily, none of my balljoint or tie rod end boots had any rips or tears, though.

There is a neat tool that presses off (from the steering knuckle/wheel bearing carrier) the balljoint and tie rod ends without damaging the boots. If all you have is a pickle fork, definitely recommend looking into this tool!

Harbor freight sells a low cost, good quality version that needs a little grinding to fit around the Porsche ball joints, but works very well when modified this way.

Sorry I didn't answer your question, but hope this info helps.

Cool Wishbone boots

Thanks for your comments. I was able to get a size of the boots and order them. I will post again with the progress. In the UK if any boots on the suspension are damaged in any way it will fail the MOT (ministry of transport test) this has got to be done every year on cars over 3 years old. Its costing people a lot of money if they are not hands on.

Cool Rubber Boots

I have done one side , it took me 45mins. Straight forward job, the joint freed off with a couple of taps. I was then able to leaver it down to get the old boot off and the new one on.
I have just taken the nut off here.

I cleaned it up well after taking the old boot off before re-greasing

The old and new boots. The new boots were 2 each

Job done, these boots had o rings to hold them on..

Paint marks on the concentric bolts, and try to reinstall to the same marks. But that only gets you close. Still need an alignment, IMHO.

Hello, no need for alignment for the boot job. They are on a tapered shaft

Yeah, you are correct. I missed the pic that showed the OP did this work without removing the coffin arm from the car.
