During the rebuild of our racing MINI we decided to replace the open-diff with an LSD. Too our surprise this is what we found when we opened the case. This is a June 04 build with apx 15,000 miles. About 5000 are testing and racing miles. Also we did not hear or feel anything.







Anyone else seen this kind of damage?

 

OH WOW-that's insane! You were soooo close to having no drive!

Were your spider thrust washers ground into the diff casing too??? How were your output gear thrusts?

Jeremy

 

The spider thrust washers were completly gone. Some damage to the casing. The output thrust washer were just fine.

The whole thing is going to the trash. But I thought some would want to see what a trashed diff looks like. I'm still not quit sure what caused the problem, except for the excessive inside wheel spin on mid speed turns.

 

Did you find the big chucks missing from your diff pin or were they ground up by the gearbox? Show us your gearbox magnet too!

Jeremy

 

Pretty insane stuff! Thanks for sharing.

 

Rich -
Thats pretty cool. One Quaife LSD please. I wonder what a dealer would say if they saw that!!!

 

The dealer would say stop loving your MINI!

I also hated the one wheel peel nipping out of corners. It'll be neat to see how my OBX diff handles some upcoming spirited exits! This clutch break-in is killing me!!!

Jeremy

 

I all ready cleaned up the magnet and no pic's. It was full of big chunks. The spider washer/shims were in about ten pieces. I surveyed the gear box and did not find any other damage.

 

Was that filled with OEM lube or something else?

 

Oem Lube.

If you can make the upgrade to the Quaife now is the time to do it .
