I bought new tires and discovered one rear drum completely broke into 2 pcs. Long ways, so the pads grab part of the drum and stop it, but the tire spins with the other half. So, it didn't brake it across the lug nuts, but along the circumference.

I ordered a replacement and rec'd an 11". I need a 12" , my truck is a w250 91.0 model. So, I goto autozones website, and they list three different models.

1. is for a semi floating rear axle
2. full float (which is what I thought I had)
3. doesn't have a pic and i have no idea what is different about it.

Can anyone tell me which one I need? Or give a part number to napa or another source..Thanks !

 

Check out the Rockauto site. They usually have pretty accurate information...and pictures.

You should have a Dana 70 in the rear. Unless you have a Non-IC 91 with a 727 and 3.07's? Then it would be a Dana 71.

 

Yes it is a full float hub.

 

I second Rock, look at the last 2 in the drum section, Centric 12367004 and Pronto BD8892.

Does yours look like those 2?
