Problem with lunch box locker in dana 30.

[JAB]

put in a quick Loc locker in front dana 30, works ok but do get periodic slipping while driving straight in 4lo.
it's a yj with 28" tires so no real stress on it, and even happens when easy on the gas.
should I have replaced the side gear thrust washers? or is there maybe a replacement spring kit to
tighten it up? this all happened on the first run with it last weekend.
I realize this is a cheep locker and I got a great deal on it, but it should'nt be slipping already??

you need to have the thrust washers in there if you didn't install them.
