|
|
I read somewhere in a thread, that one can not expect the spring strut to be completely centered in the cover hole. But I still think that mine is way off.
So I'm thinking about replacing all bushings in the rear suspension.
I know more or less what do to, so I would like this discussion to be about the parts I need.
I've been searching ebay and the web in general and seen a few options, but I am still in doubt on what to choose.
I don't want a crappy/cheap aftermarket product.
The car will only be used for cruising around, never on the track.
What will you recommend, where is it good to purchase these? Anyone with some experience on this topic, speak out. _________________ Euro 924, 1976

I used the Energy Suspension Poly for a Super Beetle, it centers a little better, but not like one would hope. Haven't noticed squeaks, but it is a rather noisy car. _________________ Mike

Not as helpful, as Dan points out there's no available replacement for the later-style (77.5-onward) torsion bar bushing.
However this is an early car, and as noted the appropriate replacement is the Super Beetle part, which is available... possibly OEM... and you might also search for Bugpack brand parts, they might have something closer to original stiffness.
That said, the link to Dan's site does provide a useful reference for me, as I ought to replace the bushings on the trailing arm pivots, maybe also the swaybar bushings while I'm in there, on my Turbo... _________________ Vaughan Scott

I thought the number 9 spring plate bushing is available?

Sorry, but that doesn't appear to be the part for the early cars, only 77.5-onward.
I did also get the impression that he would be fine with stock bushings... _________________ Vaughan Scott

The early 77 cars are different. However, pretty confident I can get the PowerFlex bushing for VW if I knew the exact year and model to cross reference, assuming the bugpack bushings mentioned above will work. _________________ erstwhile owner of just about every 924 variant ever made |

My '77 looked exactly the same as your picture. I switched over to the later trailing arms so worked with both the the later and early bushings. The Super Beetle style bushings have maybe 1/4 of the bearing area of the later 924 and 944 ones. I think I remember that even with the load off, the trailing arm is against the bump stop and the spring plate housing contacts that edge of the retainer with the ES bushings. From my looking into bushings there appear to be only 2 or 3 hardness levels of polyurethane so the ES are probably the same durometer as the softer Powerflex. When I bought mine I didn't know of Powerflex. Like the later bushings they are glued on and take a bit of effort to change. _________________ Mike

What is involved in accomplishing this? I am under the impression from previous readings that it requires some fabrication in order to install the "modern" steel trailing arms on the early chassis. _________________ erstwhile owner of just about every 924 variant ever made |

I would expect that the trailing arms would bolt right up to the earlier spring plates... I doubt the arms themselves are even different? Have to check part numbers there, I think... _________________ Vaughan Scott

It all just bolted right up. You do have to use the old TB carrier tube because it mounts with two bolts on either side rather than the later banana arm. I don't recall any problems, the poly bushings helped centering by maybe 1/8"-not much. I did change from 22mm to 23.5mm TB and without the banana arm to measure to it was a real pain get set right. I did something like making a plate(wood) that bolted to the end of the TB carrier with marks for original setting, then changing the banana arm distance to an angle, making that mark then playing with the TB and spring plate until it fit right. _________________ Mike
