About to install New bushing in my trailing arms.
But these seems to be different from the stock ones sine they have "internat slots" .
So i asume they go in a specified way.
Bently does not mention anything about this (most likely because the stock ones does not have these slots)
Slots up/down or front/back?

Alloy Porsche 944 arms?
I've only worked with steel (bug style) 944 arms. I used a chatter gun to push the old bushing out, polished the race up, then slid new sway a way bushings into place with anti seize on the OD.

The slots are in the rubber inside the bushing. So the external diameter is the same. But they will behave different depending on which way i mount them

I always just use urethane, haven't installed new rubber bushings. Check the 944 manual :p

944 Haynes checked but those bushings are not the same anyway. Checked my urtehane bushings but the inner race is a bad fit so they gave a lot of play between the big bolt and the race. The rubber vw ones are a tight fit.

Hey Fasty, hope yer doin' good, maybe you have a bad set, do you mean the sleeve is slack in the bushing? I find urathane veries wildly in tolerances being out, try another set of genuine Sway Away bushes? Regards, BBB.

Good too thxs mate,
. Is this for the Fasty or the mad bus?
I seem to remember coming accross this onetime, the T1 bolt has a bigger shank then the Porsche bolt, that may be A solution for you. BBB.

oh, it's a new project , trackcar 1302 "superbeetle" with a Honda 1000RR SC59 motorcycle engine, mounted in the backseat ,chaindrive , flappypadel gearing , turbo eventually etc
i'll like some "flex" in the bushings , so that's why i go for the rubber ones
from what i have found out , the construction of the pivot points in the vw/porsche rear trailing arm ,"are as they are". adjusting toe etc must have some flex in the bushings, also in combination with a uniball setup replacing the springplate
