OK guys, I've got the Chassis stripped on my 3000M and It's being dropped off with Adrian on Friday for assessment and repair.

I've now got the front and rear suspension units on the bench and i'm looking to strip them down so I can get the wishbones powder-coated and replace all the bushes. Can anybody give me some clues as to how to get the bottom two threaded bars out of the aluminium upright casting without damaging either?

I've been soaking them in penatrating oil for the last few days but they still look like they will never budge. Before I make a huge ham-fisted mistake, is there an easy way to extract them? smash

Cheers

If you try to force them out it will damage the casting. It's either a slow job drilling and picking them out or the easy/safe route is exchange units from Adrian. His machinist is jigged up to drill them out etc. and prices in my view are very sensible.
Look in PH parts for sale - there was a new set for sale a few weeks ago.

I drilled mine out Very Very Carefully. Good Centre Punch and progressively larger drill bits untill the pin can gently be tapped in on itself

As said if you try to force them out you may damage the upright.

The man who has your chassis supplies the pins required to refit etc

Hope this helps

Cheers Guys.

As long as i know that i can cut the bottom threaded bar to free the wishbone. I'll have a chat to Adrian about exchange units amongst other things. I'll add them to the shopping list smile

Adrian advised me to cut the threaded bar leaving something to grab onto if I wanted to get him to use his jig to drill the old bar, out as they need to grip onto something to centre the drill - he can probably explain it better than I have

Thanks Nick ...that is pretty much how it is...once the casting is in the jig the drill head can locate on to the small bit of bar that is sticking out, it makes the job that much easier to do.

Drill them out is teh way to go - I got a mate who works for British Airways to do mine - no shortage of tools there!
