3.25 lsd diff

[fnedzgn]

just bought a 3.25 lsd diff. is there any markings to tell if it is a lsd.

The back plate should have a tag saying S3.25

I hope you bought that from a credible source.

big white "s" painted on the casing, tag saying "s3.25" (not "3.25") or spinning the flanges.

I hope you bought that from a credible source.

agreed. they are VERY tough to find in good shape.....for a reasonable price.

got it from euro depot. this thing must have been outside out by the ocean. i could barely read the tag. i see the 25 that's about it. if i spin the drive flange should both sides spin?

LSD=both side flanges rotate in the same direction. Non LSD=they spin in opposite directions.

Take a wire brush to the tag.

the tag is all dimpled like acid has eaten it. both of the side flanges spin in the same direction. is it safe to say it's LSD

[PeaveyBassist]

Hold one of the output flanges. Spin the input flange. If it tries to spin both output flanges, its LSD. If it only spins the one youre not holding, its open.
