Trailing arm bushings, Tutorial? Options

[Porschef]

There’s a pretty good chance I may be removing these on Labor(!) day, is there a recommended/preferred tutorial for this procedure? I’ve seen a YouTube video or two, but they’re not as descriptive as I’d hoped for. This’ll be my first rodeo...

I don’t know what’s happened to the search feature but it ain’t what it used to be.


Thanks in advance all.

Thanks for the confirmation. Was hard to tell from the image.
@914_teener Ive also done installations identical to your description and in fact considered this the only option up to this point for renewing those bushes.
Some precision is necessary & indeed the durometer (density/elasticity) is important, although I disagree, If youve done this job you'll find the OE rubber bushes aren't actually vulcanized to the shafts. If they were the only way to remove them would be to burn them off /clean.
Regardless, ER sells a "kit" with proprietary (& patent pending!) tools to accomplish ~
Im curious anyone BTDT?
I imagine installing those soft(er) rubber units is somewhat tricky?

Well...I'll agree with you on the less expensive solution as a compromise. Elephant has bonifide engineers...I'm only a civil...they have ME's and Tarrett himself is an ME and their stuff is super nice if your customer wants something like that and wants to pay for it.

I'll respectfully disagree with your disagreement on getting the shaft out and how they did it at the factory.

I think Kent @76-914 made a set of tools that frankly were ingenious for a plumber that worked great. Think he used the stuff (bushings) thatMark sells IIRC.

Good luck.

Edit:

Ah I will recind my snark disagreement with this caviat:

Orginally I notion that they used a vulcanizing tool fixture for the shaft. This speeded manufacturing and assured the aspect of the arm and shaft. In essence for manufacuring purposes. Probably and due to the degrees of freedom that they knew that it...the shaft...may easily rotate if it needed to.

If the rubber deteriorated in the cars life cycle...say 15 years...you'd get the whole assembly..not a bushing because that aint how it was manufactured.

What they never counted on or designed was these little cars lasting 50 plus years and hence never sold a part like this.

So we agree.
