Hi all,
I am looking for a sleeve for my diff pinion. I got the National number, 99187 from the archives. This is a "Redi-Sleeve" for $35. In my looking around I discovered that there is a harmonic balancer seal listed as 88187, and this is $6. Autozone cross references 88187 to SKF 99187 which is a "Speedy-Sleeve" (which goes back to the National 99187). The FM part interchange site lists 88187/99187 as two different items (harmonic balancer sleeve, general "Redi-Sleeve"), but the specs are identical.
So I'm wondering if these are actually the same part, but the application drives the pricing?
Any thoughts would be appreciated.
Thanks,
don
