Ball Joint Separation - Struggling !!

[wixer]

Hi all,

I'm in the process of giving my NA1 a decent underfloor re-fresh and I have a split ball joint rubber on one of the rear toe links. I've tried to separate with a ball joint splitter, (the forked cold chisel type which I've used many times in the past) but with no success. I'm reluctant to keep cracking a lump hammer at the splitter with aluminium suspension arms. Has anyone had a similar experience ? and how did you eventually split the joint ?

Cheers

For the boot at the toe link and tie rod, you can use pretty much any tools including the pickle fork one that you are using and you will be forced to replace the boot by using that type of tool.

You may want to replace the entire link as an assy for both the R & L sides if the bush is already tired.
Never used pickle fork on NSX but should work.
Probably the jaw opening size is not suitable?
I normally use this type of tool for the easy ball joint task that doesn't require too much force.

Never use the silver tool in the 2nd photo, pickle fork or any balljoint separator tools that can’t apply the force dead straight to the joint shaft for the upper/lower ball joints at the upright/hub.
For these, I only recommend using the SST from Honda or the larger aftermarket one from reputable tool manufactures that can apply the force dead straight.

Many thanks Kaz. By the way, have you ever used one of these ?

I'm thinking it could be a worth while investment for NSX renovations. Probably get some use on myS2000 aswell.

Never used one on NSX but the basic principle is the same as the IH cooking hob, wireless charging for your mobile phone, electrical tooth brush, etc.
I use it regularly for the IH rice cooker and my boss is using the IH cooking for years in Japan for fire prevention.
Based on these experience, not sure it’s worth the investment at this stage.

Probably fine with the ferrous bolt but we had to replace almost all of the pan, pot, etc at the very beginning as the one we had didn’t contain enough ferrous and has to be flat so no wok.

When the bolt seizes, most of the time, you want to heat up the surrounding area and not the bolt itself and I don’t know the effect on the dacro coating although if the bolt is seized, you are very likely to replace it any way.

I don’t know the exact ingredient of the different aluminium alloys used on our NSX so not sure of the effect of IH at different part of the chassis.
Probably won’t heat up the suspension aluminium parts but does heat up the bolt or the metal collar which is good.

For my purpose, I can see it being used only at the exhaust area but then propane or even better, the oxy/acetylene burner becomes handy.
For other areas, if something seized, I would try the 50/50 mixture of ATF/Acetone as the last resort.
I learnt it from one of the member here.

Speaking as a non-chef I think Induction Hobs are cool !

Ball joint finally separated, I've never had to use so much force to split a joint before. So much so, the nut was ripped from the ball joint thread when it finally went bang !

Now to try and drill out the snapped upper wishbone fixing bolt.

Well done wixer, I thought I heard an explosion way in the distance, about midday I believe.:)

Did you end up getting the device mentioned above to do it???

[wixer]

Yep, would've been about lunchtime Pride, there may have been some loud cursing aswell ! No, just used brute force and ignorance, probably going to invest after Christmas, in the Mini Ductor. Will need it to remove the fixings for the RH rear subframe if I can't drill the snapped stud out.

part # for the SST tool?

I borrowed a normal splitter for this particular job, not the more specialised Honda recommended one.
