Ke15 Diff Change

Recommended Posts



Old KE15 Diff (Is it B-series? 5,7"?) is making a lot of noise again and i'm out of diffs. Is there other diff's that will bolt straight in with original axle? I don't want to change bolt pattern for the wheels as I have rare and cool 4x110 wheels already. With a little thinking, KE2x diff should be same as KE1x, right? Plenty of those at Finland. I heard rumours of KE7x or KP61 Starlet's U-series 6" fitting in with original axle and driveshafts but as original diff is smaller, isn't it going to hit housing? U-series would be stronger and I think it would lower revs too.


Thank you already!

If the gears are not totally destroyed you might be able to get away with lapping them, which would make them close to new. Need a proper gear shop to do this.


Then just replace the bearings, set the pinion depth properly (!!!) and you should be motoring.

early ke20s are B , later ones are U,


Did some Research some years ago and found that

U heads should fit in your B housing using B (original) axels


U : late ke20, ke30, ke70, AL25, kp61
