ball joint 1990 740

[jonesg]

!990 740 wagon, the driver side ball joint doesn't want to let go, I did the other side a while back and a pickle fork n'ammer got it out after a few whacks. This one doesn't want to cooperate with my 3 lb hammer.

I'll buy a ball joint seperator tonite and have another go Friday and saturday, but on the offchance that the seperator doesn't work I know the whole assembly needs to come off, I plan on installing new cone bushings and sway bar links anyway.

My question is this, one of the bolts holding one of the links , is it the radius rod?, has a strange looking socket, its a star shape, male end, so I need a star female socket ...but what size?

I'll buy a set but want to be certain its IN the set.
I think this balljoint has 200K miles on it.
Anyone familiar with this?

Thanks.!

Unfortunate that the usual big hammer technique has failed this time.

I have never seen just one 'odd' bolt on the steering/suspension. Is the other side the same? It is possible that someone has had this apart before and put a stranger in for some reason.

My friendly Volvo people have not come across this either.

Sorry, it is of no help.

Bill.

Bill if you're in England you probably wouldn't see one, I suspect its on the Regina only.
If the car were up on a lift I could get a better swing at it.
