Rear trailing arm bushings Helpppp

[Gre@semonkey02]

I got a set of energy urethane bushing but the rear arms don’t look right when I install the trailing arm in the bracket bushing moves over has anyone had this issue is it normal and okay to run like this or I might go buy the IE 2 piece bushing instead of this one piece

You're right, that won't work.  The bushings need flanges on both ends of the trailing arm tubes.

Ya thought so I’m Gona order the ie ones but what do I do wit these ones

You’re missing half of it. Should look like this. Are you positive you didn’t leave them in the package?

The bushing is one piece

Not sure how that won’t slide when in use. Note the gap positions below.

I'd call them in the morning and email your photos to them.

IMHO, their design is flawed.

Looks right to me. The arm won’t slide in use because either direction it hits the shoulder of one bushing or the other. Snowmobile manufacturers started using this recently claiming it saves weight and reduces friction. I think it just reduces manufacturing costs.

no, that is not right.  the gap is on the same side of each bushing, so the TA can move.  if the gap was on opposite sides, it would not move.

 

i am a big fan of STOCK bushings for the TAs....

See the thick part of the bushing goes where the flared parts of the arm

Since we're talking about RTABs, has anyone seen these? (Not exactly easy to find on their site I might add...)

There's also these adjustables: https://www.bavauto.com/bmw-trailing-arm-bushing-pfr5-306gbx4

 

I'm also curious about these adjustable bushing setups. While they seem like a band-aid rather than a proper fix (welding in adjusters), if they hold adjustment they would save a lot of work.

That's the problem.  They don't hold.  I used to get 2-3 calls a week from 2002, e30, e36 318ti, Z3 guys all complaining that their adjustable bushings wouldn't hold (kmacs/bavauto/etc.).  The loudest were SpecE30 guys.

 

I'm a big fan of the normal 2-piece IE urethane bushings.  Injection molded and ran strong for 50k of daily driving.

Pretty much what I figured. Not much friction area vs. a lot of rotational force.

 

I've got a set of the IE bushings waiting to go in. 20 years (give or take) on the previous poly bushings is probably enough.

That is the right way to install,
