Hello everyone,

I sold my OEM r154 driveshaft and I was looking if someone can take a measurement of the front yolk of the OEM r154 driveshaft and can tell me the size of the outer diameter? I am on my second rear transmission seal and its a OEM replacement and it has a small leak just as the first one did. I do have a Shaft Masters aluminum driveshaft installed and I would like to compare my measurements on this one to OEM and see if that is the problem.


Thanks.

Crap I just reinstalled my driveshaft the other day. (I have the 1st Shaftmasters Al 3" prototype)
If you would have posted this last week I could have measured it :D
