a98pmalcolm Posted March 27, 2017 Share Posted March 27, 2017 (edited) So a few of you know before xmas the Supra did a right number on me, but breaking one of the worst things to go, being the diff. Parts for them are very rare and expensive. One of the gears broke off during a launch wedging itself in the ring gear locking the wheels ruining the pinion and snapping the prop shaft well 3 months later and a solid day picking up completed parts and fitting, I finally have the on road with with an uprated prop, OS Giken diff, US spec pinion kit, solid shift bush and uprated rear diff bushes. A massive thanks to Lee Perryman and team at SRD for building my diff with some of the required parts so quickly, supplying me with the uprated SRD prop and all the advice. Paul Whiffin at Whibitz for supplying diff parts, the os giken diff and all the time taken with helping. Dan at my local Toyota for the pinon kit and track rods (damaged during recovery) And my work colleague (boss) Alex staying later after work yesterday to help with the start of the work on the car, me using his tools today and all the help with getting the stuff over the past few months. Well what else better than pictures now I guess. After removing the back plate, we found this Pinion trashed The remaining of the broken gear caused he damage to the pinon and crown I had the case sand blasted Os Giken Turned up Painted the case to prevent rusting and to make it look more presentable I also hand rubbed down the back plate to remove corrosion and painted that to suit the case Inner of the back plate all cleaned and inspected USA final drive kit Mt GF drove all my parts to Lee and the team at SRD to rebuild the diff Edited March 27, 2017 by a98pmalcolm (see edit history) Quote Link to comment Share on other sites More sharing options...

Samurai 20V Posted March 27, 2017 Share Posted March 27, 2017 Thats one of the worst failures on the torsen I've seen.. Regarding rebuilding the diff, what did Lee use for shims? The OEM shims are discontinued to my knowledge. Quote Link to comment Share on other sites More sharing options...

What do SRD charge for a diff build only if I supply all the parts the casings will be pre shot blasted and painted? The problem now is Toyota no longer stock the side shims, which is why I asked if you had the originals. if they are too thick I can grind them on the surface grinder, if too thin i have to use my very limited stock of used ones if thick enough, or my even lower stock of laser cut ones, which were expensive, and surface grinding is time consuming. So for a full rebuild like yours i would say "250 plu VAT, maybe more if lots of grinding needed. Quote Link to comment Share on other sites More sharing options...
