87 Trooper II front hub question During cold or cool weather I have a bad grinding noise in my front hubs 4X4 on my 1987 Trooper II. It does not do this during the summer..?

Answer 1

Your problem is in the lack of grease in the winter .The grease becomes clumpy and is easily pushed of of the bearing race when its cold. when its hot out the grease liquifies and lubricates better. Also after riding on the bearing with it grinding causes alot of heat build up and puts ripples on the race itself. this makes the bearing (rollers) ride on a sort of a wash board and it will make a grinding noise. Dissasemble the wheel and inspect the race by rubbing you fingernail over it to see if it is smooth. Also check the color if its anything but silver replace the bearing assembly. Also make sure the race is not (spun) in the hub it should be tight. if it is loose your hub and bearing needs to be replaced. Re-grease the old or new bearing with a bearing grease packer ($10.00 at the local autoparts store) and re-install it. also make sure you re-pack the locking hub with fresh grease before re-assembly. I almost forgot...clean any old grease before you put in the new grease. A bucket of carburator-parts cleaner works the best (but might strip the paint if left in the bucket) I repainted mine black just to make it look better since I had them apart anyway. You might want to check the fluid level in the front axle while your up there! and check your axle boots. Good luck!!!
