Anyone know which part is the following according to the attached diagram?

"Trailing Arm Front-To Cross-Member Bushing"

"2 Bushings, 2 Inner Tubes, 2 Outer Shells"

I'm almost sure it's 'Y'. It's making a creaking sound and has slowly gotten worse but can't find the part anywhere. Fulcrum suspension (who makes them) basically told me they're busy with other stuff and to wait until we make them some day. It's also thrown some other people off because they've thought the series 6 bushings would do but as I understand it series 7 and 8 are the same?

Thanks.

Your trailing arm is 28-500B, the Y location is your lower control arm pivot.....which uses Fulcrum SPF2678K.

I'd expect what they are referring to is where bolt 28-312 mounts. Have heard the toe control bushes changed in later versions and the durometer of rubber bushes varied according to the sportiness and production year of the model.

Thanks guys.

The part number fulcrum gave me was SPF2677K. You can search the parts on their website - http://www.fulcrumsuspensions.com.au/fulcrumCat/

I'm trying to track the bushings down from a spare parts place. These ones aren't hard to get to so they might be generous enough to get them for me.

I think what you meant in your post was #28-460 & #28-461. Those are not made by Fulcrum. The number you provided is for is "Crossmember Bush", it refers to the bushing on the end of the trailing arm where it connects to the rear subframe #28-500.

The #SPF2677K comes itself from SuperPro as the Outshells with the bushing pushed in as well as the inserts, so then all you have to do is push it out of the trailing arms and then push the new one (greased) back in.
