guys, I have encountered my first real mechanical problem. I hope you guys can help me diagnose the issue.
first, i have a stock m1009 that I put a 4 inch rancho lift on back in the summer and had no issues.
ok, I was driving down the road about 10 MPH in 4WD and WHAM!!! it felt like I hit a boulder. except there was no boulder. It must have been something that locked up and I skid to a stop. there was snow on the ground, so i skid for a little bit. and not an instant stop.
I looked underneath and nothing fell off or looked out of whack. I got back in the truck, and put it into drive. first thing i noticed was the speedo needle was doing really funny stuff. it was dropping to the bottom on the gauge, then popped up to 20 then back down and so on, when I shifted into neutral it did a different bobbing pattern. so i put it back into park, and then shifted out of 4wd and then back into 2wd...played with that some. finally i got the truck to hook up and I was able to make it back to my driveway.
it sat overnight, and i tried doing it again in the morn. I got the same symptoms this time, but i could not get it to hook up and go. I also hear a "whurring" noise in park and in drive...it is louder in drive.
also, I now noticed that even in park, the truck will roll backwards unless I put on the e-brake.
I have looked under the truck, and I don't see anything unusual, but I have to admit....i don't really know what it should look like to know if something is jacked up. unless it;s something obvious.
I checked my trans fluid and it is nice and red, clean, and did not smell burnt. It is a cold trans but I didn't think that it would matter as I am not checking the level, but the condition of the fluid.
so does anyone have any ideas what else I can do, check, and/or test in order to diagnose the problem. I sure do hope it's a t. case and not the trans. I can get either of them fairly cheap, but I can't really afford the labor on a trans, and a T.case will be a bit cheaper to remove/replace.
thank you very much guys, and this is my only vehicle, daily driver....so I really need to get this bad boy up and running.
thanks, pinwormfood
UPDATE: I was under the truck, and was doing some experiments. first, i drained the transfer case looked in there as much as you can. looked good and clean and the fluid was a darker red than the trans fluid, but didn't looks jacked up and I didn't see any metal pieces.
then I had the ebrake on and truck running. chocked the real wheel. had the MRS. put it in drive, and I looked under there, and the rear drive shaft was spinning, but truck no move!!! gave it a little gas, the shaft spins faster, truck no move again.
so would that be a sign that the rear is shot? logically that would seem that to me. now, knowing that, does that explain why the speedo is acting funny??? how about this one?? when I go to put the truck into park, it kind of doesn't go in nicely and grinds a bit, then I let off and try to put it in again and it works fine and goes into park.
ok, guys, i really need some help. and perhaps does anyone know a good mechanic in the easton, pa area???
