Wishbone renewal

A Ward

New member
Hi

I have a quick query regarding wishbones for the 993 - I have been changing the suspension and wishbones today, however I have come across an anomaly with the wishbone ball joint fixing.

My original Porsche wishbones have an M12 threaded rod at the end where the ball joint goes through, adjacent to the caster eccentric bolt - for some reason the new wishbones have an M10 threaded rod instead?

Having checked the parts catalogue it shows either an m12 or m10 lock nut for the threaded rod section of the wishbone - but there are no different/updated part numbers for either the wishbones or the ball joint section which suggests that the M12 has not been superceded.

Obviously as my original wishbones had an M12 threaded rod the hole on the ball joint section is M12 - but I now have an M10 threaded rod going through it (which potentially leaves 1 - 2 mm of play).

Can anyone shed any light on this please - perhaps someone who has carried out a suspension upgrade/wishone renewal?

Many thanks
 
Hi

Thanks for the replys - you are quite right; in my haste to post the question before I left the house I skimmed through the PET catalogue and misread item 19a as another version of item 19.

The threaded portion...or rather item 17 - knurled screw - part number 993 341 465 00 does indeed seem to be paired up with item 19a - part number 999 084 621 09 which is an M12 lock nut.

This is the configuration that I had fitted to my original wishbones.

However, the new wishbones -which have an identical part number to the originals and also match up with the PET catalogue have a knurled screw which is M10 threaded - hence my original posting - and both are like it??

I am very confused - I may have to try pressing out the original M12 knurled screw and one of the M10 ones from the new wishbones to get a comparison.

Definitely going to hold up the suspension install.......grrrrrrrrrrrr [:mad:]

Any suggestions or advice gratefully received - and apologies to anyone reading this who doesn't have the PET catalogue and wonders what the hell I am talking about.

Many thanks
 
Morning

Just been out this morning to have another check of the new wishbones - other than the difference in knurled screw size - (M10 compared to M12 on the originals) the only other difference I can see is the date stamp.

My original wishbones (on a 1996 993) are date stamped 94, whereas the replacements are date stamped 98 - so far newer.

Had a look at the knurled screw with regards to pressing it out - but itis not really going to help as clearly the diameter through the wishbone is smaller than the original wishbones.

I am beginning to think that I am going to have to drive the bushes out of my original wishbones and renew them. [&o]
