Metal O-Ring appeared on alignment tool

[further]

Hi all,
Long time…. 2004 5.0 GXI SX-M. Getting it ready for the season and doing alignment check. When I pulled out the bar, I noticed a metal O-ring on the bar. Any insight on what this is from? I replace the gimbal bearing a few years ago…

Ayuh,........ That is the tension spring from the gimbel bearing seal,.....

That's the inner spine on a lip type seal. Probably from the grease seal behind the gimbal bearing

Edit Bondo was quicker
