How to replace rear wheel bearing - 911 SWB 1968

[Xavier PJB]

Greetings all,

quick question : is a 2.0L SWB 1968 rear wheel bearing replacement is the same way as a later model (SC or 3.2) ?
Am asking as I do know how to on G series, but as the first series seems to change every year, am asking prior to get my hands on and get puzzled.

Flame thrower ? Big hydraulic stuff ? Axe ? Friends and beers ?

I've done it on a 1969 with steel trailing arms. Getting the old one out was the hardest part. Heat, a sledgehammer, and a big socket were needed for removal.

For new bearing installation, I used heat on the swing arm and put the bearing in the freezer overnight prior to installation, additionally I used a very light film of grease on the bearing. In my case, it took minimal force to install and has worked well for several years and several thousand miles since.

Of course SWB may be different... didn't they use 2 bearings?

Good luck! Suspension work is a pain in the a$$. (Beers always help!)

The SWB cars are different to LWB. They have 2 rear wheel bearings in each trailing arm, one inner and one outer.

Pretty straight forward job.

Why did Porsche change the design from 2 bearings to 1 bearing in each trailing arm?

The single bearing in an LWB is actually a double bearing in a single housing. It has two rows of rollers. Perhaps efficiency, only one assembly step? The total design is definitely more simple.
