Looking for info on the 3 spring loaded seals in the transfer case ( that's the way my tranny tech referred to them) on a 63 GMC Suburban 4x4. The tranny guy told me that he didn't want to take the seals out and try and adjust them as they would prob be too brittle. He silconed up the inspection covers but it still leaks...not bad though. Would these seals be available? Can they be adjusted? Any explanation, info or advise would be appreciated. Thanks EB.s63 | | |

I just called Nappa across the border in Niagara Falls and they say they have the seals. I could not find them here in Canada,and was sure I checked with Napa last July with no luck. Tomorrow I will call my tranny tech friend and make sure what I need. I just assumed this would be a Dana 20 transfer case....that's what I asked for from Napa and they agreed that the seals are spring loaded ( if that's the right term ), two are the same and the out put front seal is different. Maybe my search is over. What other transfer case did GM put in the 63 suburban 4x4?
Thanks again Bill.
