Anyone use the Weltmeister Poly Bushings places like AUtomotion sell ??? Are they any good ? Im looking for more to compliment my new Konis im almost ready to install. So Im thinking while im under these I might as well do everything.

I'm also curious about this....I bought a set for the control arms and i presed them in but they wouldn't go all the way so i ended up cutting them to size.
It does not seem normal at all to have to do this,how did you guys get them in?

Are you talking about late control arms and if so did you remove the steel liners?

The only place I have them is at the front of the front control arms. They have been on 2+ years with no issues. As the previous poster says, you have to remove the steel liners for them to fit.

CRAP,omg i cant believe i forgot about the steel liners.
Any DIY around on how to remove them?
Thanks....

Here are some pics for your amusment,

Thanks for sharing and I admire your courage to post pics!

It seems there are a couple ways to get them out. Some use a hacksaw and cut the liners, then pry them out. I used a cold chisel and was able to deform the ends of the liner and then drive a socket through the other side and force one liner out. Then I drove a socket in from the other direction that was just slightly smaller than the ID of the opening in the control arm. Either way you do it is a PITA IMHO. You just have to use patience and take car not to damage the aluminum arms as it could lead crack/failure in the future! Good luck, Rome is a great place and wild place to drive.

Well i was hoping for something more simple but i'm sure i can get the suckers out...
Thanks alot for the info!

that it is lol.......


ps:sorry for hijacking the thread and thank you WizPorsche944,if it wasnt for you i would have left the liners in.

One of the 944-Spec racers recommended Delrin for the front two-piece bushings. He said the Welts would deform over time. They're fine for the caster blocks (the only place I have the red Welt front bushings). He may have only been referring to the early steel arms though.

If you just street drive it, you should be fine.

Yep the PB-1019 (forward location for steel arms) are crap. They might be ok on the street, but I tore through 3-4 of them on the track. There were so bad when I talked to paragon they went out and got racer's edge to make up the delrin ones that you see pictured. I have run in the delrin front and red in back (just like shown) for years. That set-up works fine and will in fact out last the control arms.


I have alose used the PB 1030 (Front aluminim arms) in my street 944 turbo. They work, but looking back I am not sure they are really the best. The seem rather sloppy.

Thanks for posting, Joe. You are the racer I was talking about

I put about 20k miles on a set after i rebuilt the arms, about 20+ auto-x's also. They worked well and are a good replacement for stock. Though they say that they will not hold up to track driving, i think they did fine. Where most people see wear and tear with them for track use is actually the steel sleeve which slides inside the bushings wears out causing excessive play in the bushing.

For the steel sleeves pressed into the control arm itself, depending on the condition they are in i have used two different methods on the 6 sets of bushings ive replaced (on my own car and my friends cars). Either i will use a punch to work the sleeves out working around in a circle.. once the sleeve is out enough you can use a flat tip screwdriver to continue prying it out, then eventually go with the channel-locks or vice grips to work it out the rest of the way. The other method is using a hacksaw to carefull cut the sleeve so its easier to deform and subsequently work out.

To make it clear here is what happend to my red bushings.

these got torn up in the aft part of the control arm barrel. This allowed the control arm to slide back and rub on the crossmember.

This was of course a racing application and would only happen in the right front corner of the car. I think alot had to do with the heavy braking loads on that side of the car for one corner.

If I replace them with OEM rubber bushings do I have to remove the steel liners ?

87944turbo

No, you only have to remove the liners if you install the Welts or delrin or spherical bearings etc.
