hi, i recently bought a rear wheel bearing bc mine is shot. when i got it (from an ebay supplier) it was way too big. so i got the kit from black dragon, it was the same exact bearing. my fb is a 1984 S model but it has a lsd swapped into it. could my rear axel come from a 81-83? would that mean a much smaller wheel bearing? or do i have to try to figure out what the PO put on the back of my car?

 

Find the serial number on the axle. Might help identify it

 

Super simple way to identify big-bearing from small-bearing disk housings at a glance.

Look at the caliper mounting bolts vs. the bearing retainer bolts. On a big-axle housing, the caliper bolts will be parallel to two of the retainer bolts on the same side. On a small-axle housing, the caliper bolts straddle the point in the retainer bolts' triangle.

Super simple!

 

im assuming you have the axle out already, you can count the splines and thatll tell you if its the big or small bearing rearend

small=24 spline
large=26 spline

 

There should also be numbers on the bearing itself. You might need a magnifier to read them but that way you'd have the correct replacement or it might work to cross over to another brand more easily available, Precision, Timken, SKF or .......

 

now someone really knows his bearings!!
