Does anyone know of a suitable replacement front driveshaft boot for a 1999 K2500 Suburban? It covers the yoke splines where the driveshaft attaches to the front output of the NP246 transfer case.

GM part numbers appear to be 12471199 and 15084601, but both of these are discontinued and I can't find a replacement anywhere. I am rebuilding the transfer case and in the process discovered that the existing boot has multiple splits and is in poor condition.

Thanks for those links - I hadn't come across those.

I found GM 12471527 but the ends are the same size so it won't work.

Close but nothing exact from Spicer unfortunately. Existing boot is 1.75" on the large end and 1.38" on the small end. 3" long but that dimension isn't critical. I don't suppose you are aware of any other suppliers?

You measuring the ID or OD of each end of the boot?

Actually did you measure the area of the shaft it clamps on. Any flexible mm material will have some give in it. I would start calling any drive shaft rebuilders. What about ford or Dodge they have 4 x 4. Yeah , GM doesn't carry it, so you have think outside the box, be creative. What about any of these?
