Hi @JohnVallo great information. You sound like you know a lot about diffs. I wondering if there is something wrong with my rear differential. We have performance pack cars in Australia. Early this year I had diff problems which the dealership said was LHR diff bearing. The replaced it but I have felt the back end was never quite the same. It seems to lose traction a lot and feels like its the LHR. It's just not as stable. Anyway last week a strange thing happened going out the driveway. The RH rear tyre was on uneven ground, and slightly in the air. When I accelerated the wheel just spun and the LH rear didn't get any traction, the car did not move. I thought this was strange and reversed a bit to even the car up then drove off. Should this happenas I thought as a LSD it should have engaged the other wheel and made traction......is my diff rooted. As I said I've never been 100% confident all was righ since the fix. Any ideas
John may not know (or I may be wrong) that your Aus PP spec car, like our euros and UK’s gets the trac loc and not the Torsen diff - that may result in a different responseA Torsen rear-end will respond this way.
To get traction when one wheel spins, just pull emergency brake a little to put resistance on rear wheels and then both rear wheels should get traction.
@JohnVallo - I know that TBR can be altered by elements of the design and components, but are you aware of any TBR differences between the models across the mustang range i.e. does a 350r or a 500 CFTP have a different TBR when compared to say a PP1 ?
I ask because I picked up a rumour (can’t remember where from …) that the aftermarket Ford Performance Torsen may be different than the factory Torsen.
Following on from that, I understand that TBR after manufacture can be altered a little by oil weight and slippiness i.e. a thicker oil will give a lower TBR when compared to a thin oil with a load of friction modifier. Do you have any experience with this ?
Finally, are the standard Ford drain and fill plugs magnetic ?
Sorry for all the questions, but you seem to be the best guy go ask … !
Cheers,
WD
