Axle Code

I am putting outer axle bearings(wheel bearings) in my 04 Ranger. Axle code R7

It has a 8.8 diff cover 10" x2.5" rear brakes, 2.25OD x 1.375 ID bearing. But for

some reason the 6408 wheel bearing I got from Advance are WAY too big.

The Torrington bearing that came out DB67309 crosses over to a 5707 which they show as a 7.5"

The 7.5 and 8.8 are the same except for the center section, take the same bearings ect.

Not according to advance and autozone

7.5 takes 5707
8.8 takes 6408

Jeffs bronco graveyard also shows different part numbers as well

The bearings and axle shafts are the same for both the 7,5 and 8.8 28 spline rear ends, It's the 31 spline 8.8 that takes the larger bearing.

Most Rangers came with either the 7.5 or 28-spline 8.8, which use the same bearings. Only a few, namely the FX4 models, came with the 31 spline 8.8. The parts store computer SHOULD list all three options, but it's possible and likely the computer erroneously omitted one or more of those options.

In the future, if you're looking for rear bearings or seals, just lie to the parts guy and tell him you have a 7.5.
