someone told me that LS and b16 have a different bearing on the diff. The ls and b16 are a reg pack bearing, and gsr and type r are needle bearing. I opened up my tranny, and found its a pack bearing, I just wanted to double check with you guys. Because when i bought this tranny the guy told me its a gsr tranny.

 

is thier not a number on the front of the tranny telling you what it is?

 

Where?

 

that is the type of bearing found in a b16, type r, or ls (roller style bearing)


the gsr has a tapered bearing......


for the record some gsr's were y80 and some were s80....
likewise some ls's were y80 and some were s80 so the number alone cannot be used to determine what kind of tranny it really is.
i also bought a tranny under the impression it was a gsr and when i opened it up to put in my new FD i found out it was an ls.

if you want to be positive of what u have count the teeth on the ring gear (the one bolted to the diff) and divide it by the number of teeth on the main shaft (the one that is touching the ring gear)

a good way to do this is to use a bright colored marker to make a mark on the first tooth so you know when to stop counting.
LS = 4.266
GSR = 4.4

I got a 4.6 does that mean its a b16 maybe?

 

I think that the newer cars use the sealed bearings and the tapered roller bearings are on the older units. From what I understand, the dealer only sells the sealed bearings now and are supposedly interchangable with the older tapered style.

When you replace your diff bearing, you just have to pull the roller bearing off the diff and knock the outer race out of the housing. Shims are still used with the new style also. This info is from some other posts I read recently when I did a search on differential bearings. I am relying on second hand info tho, so I hope it is correct.
