So the rear axle in my 99 4r is leaking into a drum again. (breather relocation done way back, did rear bearings and seals a couple years back, just did driver side again 6 mo back and now found passenger side leaking.) Incidentally the wheel bearings in the toyota axle are almost identical, minus the snap ring groove, to the front and rear main-shaft bearings in a t-18 transmission and I'd love something beefier.
I tow a lot, (have airbags) and have a Sterling 10.25 with posi sitting around and am planning to swap that under the back of the 4r. Front swap can come later but for now just want to get the rear sorted. Gears are the same as the 4r currently (4.10) so don't need to open it up and the posi in the Sterling works. Plan is not to really lift it or change the links, just copy the brackets on the current axle onto the Sterling. (Well within my welding capabilities.) Might move the axle back a little to keep from changing driveshaft length and use an adapter.
Questions-
1- Can anyone point me to build threads that used this axle? I tried a couple of searches both here and web in general but didn't find much about this axle specifically.
2- Has anyone ever tried notching the outer lip of the brake drum to mimic a much larger (and therefore more spaced) version of the ABS tone ring to get ABS and speedo sensor to work? Having looked at them when I had them out, they look like a simple magnetic pickup creating a pulse when metal passes by.
3- Anyone who has done a swap like this- would you recommend a larger diameter master cylinder? I'll compare diameters of wheel cylinders while apart, and obviously if the pedal doesn't feel right can adapt but curious about experiences. As I recall, there are quite a few threads about putting in larger master cylinders to accomodate a TBU so the how to on that shouldn't be difficult to find.
Thank you for your help.
