The 3800 tends to be a bit of an enigma as you well know.
So I was hoping someone might have a list of seal part numbers.
Thank you | | | | | Joined: May 2005 Posts: 8,878 . | | . Joined: May 2005 Posts: 8,878 | Seals are one item that I find quite easy to get at the auto parts stores either by the numbers on the old seals or by the dimensions of the bore, shaft, and thickness.
Sometimes they can look it up by application but it is still smart to confirm dimensions.
What seals are you looking for? | | | | | Joined: Oct 2014 Posts: 9 New Guy | | New Guy Joined: Oct 2014 Posts: 9 | At the moment I am looking for the output seal for the 4 speed in my 48 3800. A few weeks ago I was looking for axle seals by application without pulling them. | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy vermont48, welcome, the transmission output seal should be SKF p/n 22340 $11.66 at RockAuto, the rear wheel seals should be SKF p/n 28426 $7.63 at RockAuto, hope that helps. | | | | | Joined: Oct 2014 Posts: 9 New Guy | | New Guy Joined: Oct 2014 Posts: 9 | Hey!
