The IRS is out and I am wanting to replace the seal on the fwd part of the pumpkin. The original intent was to “refresh” easy stuff, and inspect for additional items. I already have all four dampers and springs replaced. Sway bar bushings and link bushings. Also replacing all other rubber sub frame mounts and trailing arm bushings bushings.
I have heard it is important NOT to over tighten the nut (which is kinda obvious anyway) that holds the flange on because it could “crush” the spacer in between the inner and outer bearings, if it has that type of spacer. I have also heard that there is a solid type of spacer between those bearings. The exploded diagram on the SNG website does not show this spacer…at least I could not ID it.
My gameplay would first be to check the manual for instructions of course, and then mark the positioning of the nut on the shaft as well as the flange. Count the “number” of rotations as the nut comes off. I assume the flange will then come off, perhaps with a bit of coaxing from a puller. Then the seals look to be behind that flange.
Any tips on replacing those seals appreciated; tricks, short cuts, Diff Oil preferences etc etc.
