sorry for the late reply, been in the us for a couple of weeks.
bought ring & pinion 4.10 for my grand cherokee which works much better with the 1UZ engine and gearbox. original was 3.73 - not good !
anyway , if anybody got a ISC motorhousing. old model 90/91/92. The one you can pull apart ! don't need the motor , bearings , spring etc. just the round black housing as my one is broken at one of the 3 screw holes. glued and siliconed it. don't know how long it will hold .
live in Thailand !
thanks
Heiko
