Transfer case Seal

[rkn2903]

Hello, anyone have the part number for the right side transfer case seal on a 99 GMC Sierra 1500 4WD z71, and is there more than one seal because mine has a small wet spot where i think the seal goes, and I want to repair it before winter? Thanks

Not sure what you mean by right side as there really isn't a right side seal on the transfer case. If it is the rear output shaft seal (goes from transfer case to rear differential) the part number is 12547638 I believe. If you are talking about the right side seal on the front differential (front wheel drive shaft to front diff) then it I believe it is 12479012.
