Guys I got some poly bushes for my sierra lower arms and when I trial fitted the arb ones they were a little loose in the hole in the arm.

Im thinking they might expand a bit once tightened but wondered if anyone else came across this?

I know the ar wont fall out but Id rather it was properly done.

Thanks.

I'd expect them to be a tight-ish fit in the arm and then you'd tighten the nuts up with the car on its wheels so the rubber is not stressed when the car/suspension is "at rest".

I used them on my sierra xr4x4 road car and they were rather loose, both for the antiroll bar to tca joint and for the inner tca bush inside the actual arm, but neither caused any issue.
