|
|
Not long ago I bought a Celica GT RA40 and I need a LSD.
So I need help with some issues.
Is it so that every F-axle and diffs fit between each other?
Is there any difference, like the T-diff, that I need to look out for?
Will be most thankful for tips and link to where I can buy a F-diff with LSD that will fit my Celica F-axle.

You can buy just the 'Torsen LSD' itself and have it installed into your current F-series diff housing.
The detroit true-trac is a torsen lsd for the 7.5" toyota diff, but unlike the factory torsen it doesn't break at 400 hp (supposedly). It was originally designed for the 4x4 toyota front 7.5 and is meant to take a lot more torque than the OEM one - afaik.
See more info here:

OR kaazusa has found which one will fit the 82-85 F-series independent rear susp, which is a direct swap into the older solid axle F-series diffs

Thanks.
So all 7,5" F-diffs fits each other, IRS/IFS and solids?
How about such things as ring gear bolt pattern and number of driveshaft splines?
No worries...?

Hi,
You want to remove the torson diff, or are you looking for one?
Thanks,
Ron

Ring gear bolt pattern is the same for all 7.5" toyota gear sets, Driveshaft splines are the same (28mm O.D./27spline axles).
To fit a 'detroit truetrac' torsen lsd in a RWD F-series housing you need to use the carrier bearings from the 95-04 hilux (1st gen toyota tacoma here in the states) part #:
90368-50006 | Carrier Bearing
All this info is covered in the linked post - afaik.
