Hi guys,
I know there are already a ton of threads on leaky rear axle seals, but I wanted this one to focus on the special tool needed to pull the axle shaft off the hub to replace the bearings.
I'm referencing the original axle seal how-to thread here:
Rear Axle Seals: The Ultimate Information and Replacement Thread (3rd gen)
AFAIK, the dimensions required for the special tool are (please verify these dimensions if I am wrong, or if the tolerances can be revised!):
4 holes, each 11 mm diameter and arranged in a square
89 mm hole-to-hole length
125 mm diagonal hole-to-hole length
75 mm center hole. Required to clear the retainer and ABS ring.
~0.6 meter length, from plate that secured to wheel hub to end of tool that rests on the hydraulic press fixed surface
There's some great designs, my favorite is the one where the guy incorporated a bearing puller to clamp the ABS ring such that both the ABS ring and retainer could be pulled off and re-used (instead of having to cut and chisel these parts off). However, all these designs are welded together, which is something the average backyard mechanic like me might not have access to.
I would be interested in hearing if anyone has successfully fabricated this tool from more easily sourced materials and fittings (eg. hardware/industrial supply store)? Or have you tried other methods of getting the axle off that worked? Ideally while keeping the retainer and ABS ring intact.
If so, please share your ideas!
