brake drum rubbing dust cover/backing plate

brake drum rubbing dust cover/backing plate
Your donations help keep this valuable resource free and growing. Thank you .

My rear drums are rubbing my dust covers. I have moser solid axles, posi and 295/50/15 tires. The back end is fresh and is not wornout. It is wearing a bevel on the edge of the drum. Im thinking about either making a spacer or just maching the drum off some. It has done this since the raise end was rebuilt and the big tires were put on, but it ‘s getting a little worse and needs fixed.

Has anyone always had this issue ?

Did this starting signal after the raw axles were installed ? Any spacer consequence going on that lets that axle float in and out excessively a lot ?

Yes everything was done at the same clock … .410 gears, posi, moser axles, tires …

New brake drums excessively ? Dave Z

No old drums, but they look great. Had them checked at the parts store a couple times.

believe it or not, the factory made a shim for this topic ! IIRC it was for when the hubs were pressed on the axles excessively far. It looks identical to the front rotor shim but it ‘s thin ( .06 ” ? ) and has three holes for the drum retentiveness bolts. If person will look up the PN for you and possibly you can find one with a dealer search. actually, Kennedy American may flush have some so I ‘d start there .
Ouch

I think I may have to much axle end play ? I had the drums trimmed a little at my work today, put them back on and ran it on jackstands … still rubing/scraping. So I knoticed you could pull the wheel back a 1/4 ” or sol … did that on both sides and …. no noise … .then pushed em in and noise again .

ohio ohio — sounds like one or both axles are besides short. unlike AMC rears have different axle lengths.

there ‘s a set of shims that need to be inserted on one english alone to set the axle end play to some minor count ( its in the tsm, ca n’t recall ) decidedly under .010 ”. not 1/4 ” ! !

You ‘ll need several shims on the driver ‘s side .

one assume the bearings used were sealed ball bearings ? if so they will not end play adjust like the factory tapered bearing axles.
1/4 inch play in the axles is not adjust. if they used the factory style tapered bearings that may be your problem. all the moser axles i have installed used the sealed musket ball bearings and a crusade on sleeve to keep them in topographic point. besides, on a 2 piece twin fascinate posi they recommend removing the spacer in the center.

after thinking about it some, iodine think if you pull the axles ( which i would do soon ) you may find the incorrect bearings installed. one cant intend of any other way they could move in that far. the machine surface inside the axle tube should keep the correct hold from moving inward and the back plate/bearing retainer would keep it from moving outbound.

hope this helps
