T-case Temps

How warm or hot do transfer cases get under normal driving conditions? Yesterday i drove my truck about 30 miles home from work and when i got home i crawled under to look at something. I put my hand on the t-case and noticed it to be really warm. Warm enough that after about 10 seconds you are ready to take your hand off. Is this anywhere near normal? My exhaust does run close to the t-case so is it possible that the exhaust is helping to heat it up. I checked the grease in the t-case about a month ago and it was totally full. This heat really confuses me because i dont think that it should not be that hot, at least not in two wheel high. Does anyone have any insight to this problem or is this normal to get that warm?

Re: T-case Temps

when you say grease in the tcase, I assume you mean 80-90W. Doesn't sound right to me, I don't think it should be getting that hot. any vibration that might point to a bearing going out?

Re: T-case Temps

I am picking up a vibration at about 55 mph and above while coasting. I dont have the vibration much while I'm on the gas, it is more when I'm going down a hill or such. Oh, yes when I said grease i meant 80-W90, sorry. I'm thinking that bearing may be going out. I have heard on the board here that there are rebuild kits for these t-cases, anyone out there have that contact info for them. I'm kinda worried but i think that for now I'm going to keeop driving it to see if it gets worse.

i might be totally wrong, but isn't a t case supposed to have auto tranny fluid in it?

<font face="Comic Sans MS">A *chain* driven case (with the NP203 being the only exception since it gets 10w40) gets auto transmission fluid.
