It depends on the current condition of your needle bearings.

Unless it's broken you don't need to rebuild the case. I just pulled apart an 85 forward shift and an 88 top shift to install my 4.7s and get ready for my duals and both cases looked brand new inside. I was going to rebuild the cases but after seeing the insides I can save the money for other things (Longfield output).

My newly built dual case failed a few months ago and the needle bearings in the fwd transfer case that the low speed gear rides on were the initial point of failure.  The fwd case was the stock one out of the 89 4Runner and the rear was a MC 4.70 unit.  It cost me more than $100 to get  back on the road.

If you're going into something for a rebuild, I always like to remove all doubt of future failures when possible.

I wouldn't worry about them. Inspect them thoroughly before reassembling the case. Transfer cases are low mileage in the first place.
