Wondering if any one can give me a part number and source for a roll pin keeper for the a604. I figured since I have the diff cover off I might as well add the keeper just in case, but when I called the dodge dealership the parts guy had no idea what I was talking about and couldn't find anything on his computer.

 

The part numbers are mopar numbers, Roll pin 6503827, there is also updated pinion shaft and bracket too. Shaft 5134956AA and bracket 5134957AA.

 

www.transgo.com offers case savers. they are plates that bolt to the ring gear which prevents the diff pin from walking out in the event of a rollpin failure. 604 CB


I ALWAYS install these when i do a rebuild. I live in the snow belt and these case savers have saved a lot of major catastophies. and they are cheap under $20 is what I pay.

 

I click on the site and mountain climbing gears came up. The part numer I gave is a plate or bracket that bolts to the ring gear.

 

check again. click on the link go to the part number I listed and it's case savers that bolt to the ring gear.

 

It came up with the transmission part site this time. I wonder what happen the first time.
