Default Rear suspension

Winter time means 993 TT project time.
I am in the process of replacing the rear bushings with new ones from Elephant Racing. I need to remove the right wishbone arm but can't get it loose. It's stuck in the wheel hub. The left one is off. Any good tips?

I have found that hitting it or tapping the head a few times with a hammer and adding liquid wrench penetrating oil has helped. (Blaster) Spray it and tap it and let it sit for a while. Do this at least 2x. Hope it helps.

One more thing is you could heat it with a blow torch and cool it with water, then heat it again. This eats away the corrosion.

Please don't heat and cool your aluminum suspension components with a blow torch and water! Not very nice to the properties of the alloy. Get a big flat head screw driver, and use leverage to force it out. Smooth, slow "suggestion" to remove it w/o damage/injury.

Default Unsuccessful

Thanks for the tips but it's still stuck.
I have soaked it with oil. I'll give it another try tomorrow

Are you trying to seperate at red arrow, or the inboard (yellow arrows)? If the red arrow, can you use a sacrificial pair of nuts, to pound and possibly crack it loose? Have a helper try and get a ball joint separator in, and give some slight tension (w/o tearing boot/damaging joint), as you strike on nut. Once that initial crack is done, it's good to go. Inboard, (yellow) should be easy to pry out. Get the nuts set up, use a long punch to reach from top camber link, trying to get a good hit on it, vertically. Hope this makes sense, and/or helps.Name:  IMG_9838.JPG

I've had BMW balljoints that were stuck solid. Banging on the hub with a sledge did nothing. A ball joint separator was required to break these loose and when it came apart it was like a shotgun going off. May need one in this case if you have the necessary real estate to get it in there.

I used a ball joint separator and tore the rubber boot. Be careful.

Thanks for all the input guys. I have tried all proposals. Need to be careful with the rubber boot.

One idea is to put a plastic bag with crushed ice on the hub and the bolt and leave it there for at least an hour.

Btw - I did the elephant bushings. You're gonna need a press. Are you going to replace the kinematic bushing? I did that one too but am not sure that was an upgrade. You will essentially be removing what Porsche designed into the suspension.

Default Torn rubber boot

Greg,
Were you able to repair the boot or did you buy a new wishbone arm?

Smile Problem solved

I borrowed a fork from the local garage. Hammered it in the ball joint and then hammered the nut from above and finally the wishbone arm loosened. What a victory

Now I have removed all the old bushes and the arms are up for a thorough cleaning.
Will get the new bushings pressed in next week.
