diffs and 4wd

[TonyN]

Thought mine was LSD due to sticker being present on rear diff casing [all text missing though], but after wheels off ground recently noticed they acted like open diff [wheels turn opposite when rotating] and the VIN code on bulkhead finishes off with a 4 against the Axle Code so must be open

Toy LSD arn't all that tight, plus its probably well worn by now, i doubt you'd notince it spinning by hand.

Cheers, so if I put LSD Oil in will this knacker the diff if it turns out not to be LSD.
