Finally got around to changing the ball joints in the wishbones.
Used the YouTube video from Roaring Tigers Garage blokes Stephen and Ryan. You definitely need another set of hands for this, so enrol a friend to help (thanks for your help with this one, Martin)
Getting the wishbone bushes out is easy, I followed Chris Walford's front control arm bush tutorial and used some Superpro bushes. The Superpro bushes come with shims and are easy to fit. The bushes were from Design911 and are listed for 944 S2's. The part is number SPF2935K and is listed on the SuperPro for Porsches 911,964, and 933's. Looking at the Powerflex site, their PFF57-101 equivalent bush fits the 911,964, 933 & 944 S2. There are also fitting instructions for the kit.
Once the bushes and the bush cups are out, its a good idea to clean up the bush housing as mine where really rusty.
I used the bolts and washers to the bushes firming in so they could slide in the front sub frame. It's a tight fit and they would not go in without 1st being pulled in with the bolts and washers
The ball joint kit has grease nipples installed, but are small 6mm ones, and my grease gun did not fit them, so I needed to buy an adaptor for the gun to accept the 6mm nipples.
Porsche posted a tech bulletin in September 93 regarding the suspension upgrades needed to run 17" wheels. The bulletin states:
New caster eccentrics, rear mounts and nuts must be installed in the front control arms. This change is necessary due to a change in caster specification on vehicles equipped with Porsche 17" wheels.
Interestingly the arch lips have already been rolled, which was also recommended in the Tech Bulletin
Front suspension Part Number & Quantity Required
1. Rear Mount 951 341 023 00 x2
2. Eccentric 951 341 431 02 x2
3. Nut (torque to 100 Nm) 900 910 115 02 x4
These 968 parts and are required for the additional caster needed for 17 inches wheels.
As I intend to use 18" wheels, this modification is definitely needed. Some info on the upgrade can be found
here. However, it does not recommend running larger than 17" wheels. There was an option on the 968 for 18" wheels, and lots of the guys on the Porsche 944 forum run them, so I don't believe this will be a problem with the correct castor settings, as the front suspension will be identical to a 968.
