It seems to have gotten a little better. I did try to engage the difflock and the light comes on no problem. Im suspecting a bad rear axle because thats really what it feels like. I checked the diff fluid and i checked the axle nuts for tightness. Will put the car on the rack at kerven on monday and inspect the axles.

On a lighter note, I replaced some of the worn out decals on the sides today and installed a boost gauge! w00t
