I had my trailing arms shot blasted and powdercoated.

However the new rear bearings don't need pressing in they just slip in with a gap remaining.
2 questions I have.

1) does the trailing arm bearing housing have a sleeve, which I am missing?

2) Are there different size bearings? - I have 75mm outer diameter for the bearings.

A picture speaks a thousand words. So here are 2!

I need to confirm the internal diameter. I don't understand why this doesn't fit.
Any help would be much appreciated.
Thanks

Hi Rav,
I got it from ECP a bit back. I was trying to find the original bearing to confirm fitment. I am confused. :?

Hello TPS,

So the sizes differ between these then? The arms are from an ABS car a rolling shell I bought. I will have to check on the bearings.
