t case linkage sloppy

the case was slipping out of 4 low so i ajusted the linkage and it shifts into lo great now but still pops out of hi and low from time to time but it is not the same as before. it used to come out under load and now i can be just putting down a trail in 4lo and it slips out the linkage seems to be real loose...is there any thing i can tighted......i can shift it with one fingure.....dont think it should be quite that easy thanks

There's a number of bushings, 4 I think, available from the dealer. They were a few bucks each, IIRC. I dunno if that will fix your problem, but I replaced one of them, and it fixed the fact that I could not get into all modes.
