    lately, when i engage my 1985 k20 into 4 wheel drive, i hear a whining noise. the hubs were greased within the last 6 months when i redid the front brakes. could it be from the transfer case? also, is there an easy way to check the fluid in the transfer case and is there a filter on same?

    No filter for the transfer case - Checking fluid level is performed by removing plug on transfer case - oil level should be just under plug hole if I remember right. The 85 Chevy K20 I used to have always had a bit of a whine to it in four wheel drive - I think tires and road conditions also contibute to the whine. However that aside, those old transfer cases were tough in those trucks neither myself or anyone I new ever had one go bad. Check: transfer case fluid level, universal joints (front driveshaft & at wheels), check front differential fluid level. Hope your problem is minimal - I sure do miss my 85 Chevy that was one good truck.

    check the fluid if you have an aluminum tcase it is ok to put in atf but I would recomend getting some synthetic manual trans fliud for it if you have a cast iron case 80 90 gear lube is what you need (synthetic recomended) draining your current fluid and installing synthetic may help the noise but I have heard many that jjust make a noise and thats that but if it is heard over the radio loud exhaust or tires you may want to take it to a trans shop to get a pros opinion its hard to dia noises over the net
