Many thanks for that. Could you see if there are still any 4:88 ratio Wheel and pinion still available at the moment?

Also the calculation you did for the 4.88 ratio did you include the overdrive gear I have in your equation thanks LEE

Calculations included the OD gear at .78.

The 4.88 was in a two speed axle, a model 16244. I do not know what interchange there is between models. But I doubt the two speed innards would fit in your carrier, and it's a question as to whether the entire two speed center section would fit in your housing.

Found this one, 4.56:

Ahhh! Post 4 answers the question--the 17221 slides right in where the 17121 fits. Read it carefully about spline etc.

Some for sale here. Again, you'll need to confirm the ratios and spline counts:

Hello, I wonder whether you could be of assistance again please I have located a new gear wheel and pinion 4.88 to one ratio. It’s for a17121 diff but I have asked them if there’s any way of doublechecking this will fit my diff because of the cost of shipping it over to the UK. I don’t want to get the wrong part. They have now asked me for the gear wheel numbers on the existing 7.17 ratio, differential is there any way of finding these numbers without physically taking the diff out of the axle casing? Many thanks, LEE.

Pretty sure it's got to come apart to confirm numbers on a gear set.

Maybe another member will chime in.....
