I was told that grease can leak into the transfer case, would this be an issue on my make and model and does it only pertain to the front driveshaft?

Hi there, I am Cam.

You are feeling what is called Slip Bump. What is happening is the slip yoke into the transfer case or transmission is binding under power. The fix takes about an hour and if you can take it off, yourself and have a small file, then you can do this yourself. Using a small triangular file, file the edge of the splines in the slip yoke. 1-2 quick strokes is enough. You just want to smooth the corner off. Ideally you will not be able to see a difference, but when you clean it out and lube it with grease, then install it, that slip bump will be gone.

Thank you, ***** ***** is OK to grease without having to worry about it getting into the transmission fluid in the transfer case? Saw a bulletin to not grease these on 4wd, but not sure if that applies to my make and model or if it was the front drive shaft only. Lastly, should it be a thing layer of grease or should I hit it pretty liberally?Thank you,

Slight layer of grease on the splines is fine, filling the yoke will push it into the transfer case.
