When I put py transfer case into 4L it makes an awful grinding noise. But only when in 4L. Not when it's in AWD. Ideas?

is this when it is already in lo or when you are trying to put it in lo?If you don't do it right,it will make a lot of noise when you try to put it in lo.You have to put the trans in neutral,slow down to about 2 or 3 mph and then put it in lo.It might grind for a split second,that is normal.

XJ is right, if it is making the grinding while trying to get it into 4LO then u moving too fast/tranny in gear. do what XJ said, I recommend coming to a complete stop and placing tranny in nuetral then put the transfer case styraight back to 4LO without stopping.

No, I'll be at a complete stop, trans in neuteral or park, once the lever is engaged, and I begin to roll... GGGGRRRRIIIND

It sounds like you have an internal t-case problem.I would check the adjustment of the linkage to make sure it is going all the way into lo

Would that be pricey to check or fix or is it something that someone with basic mechanical knowledge can fix?

We were having the same problem with out Explorer, completly different setup but the same symptoms. The problem turned out to be that the tcase wasn't fully locking into 4lo, from what I remember it wasn't a very expensive repair, but this could be something entirely different.
