Rubbing drums

Post by stevend34 »

Hi Gang, after replacing rear wheel bearings, brake cylinders and brake shoes I noticed a rubbing noise. Figured it was the shoes bedding in, however upon inspection it’s the drum hitting the backing plate. Happening on both sides. See photos
The only things I can think of is the wheel bearings are wrong or I’ve pushed them in to far, or the backing plates both somehow bent in the process. Can you actually push the the axle/bearings in to far? Should I just leave it and let it work itself out? Any comments? Suggestions?

I think I remember 2 types of wheel bearing, with and without a built in spacer.
But it has been a while since I worked on a Sierra.

Bearing in backwards maybe, if it is actually possible to do, may let axles go in too deep.

yeah i know what you mean; expected: onside of the bearing has a lip on it. These bearings where the same both sides. It could explain it.

cheapo bearings in purchased: https://www.onlineautoparts.com.au/prod ... /ZPN-01832

Chucked out the old bearing so i don't have a comparison. Anyone got a bearing kicking around the could measure for me?

My lwb 1.0 litre had the spacers.
Was no other option then
1.3 and 1.3 widetrack some had spacers, later didn't.
I think people used the spacers from older models, so that they could use the cheaper more common bearing.
Probably not an issue now days?
We as wheelers mess with diffs and stuff, so any model could have mixed parts.
No idea if it is your issue, but worth checking with a more techy person.

Hi Steve.
The back axles on my nt ute have a spacer. Its about 3mm wide and is shaped to fit the radius at the end of the axle....if that makes sense. The spacer goes on first, then the bearing, then the retaining collar.
I have seen bearings that don't need the spacer. They have a wider inner part that that takes the place of the spacer.

Don't forget to put the brake back plate on before the bearing... :roll: . Done that before.
Regards. Wayne.

yeah know exactly what you mean. my bearings did not come with a seperate spacer, nor did they have the colar. That will be my issue for sure.
there is a 5mm difference according to new ones ive looked up vs mine.

Yes I have put the bearing on before the backing ate too haha bad times.

The extra protruding but of the inner race on the bearing goes onto thr axle first so at the end it's closer to the wheel than the diff according to youtube

just to finish this one off; the solution was purchasing and installing the correct wheel bearings which included the 'shoulder' built in to the bearing. No more rubbing
