Okay so an update, I installed the new tach and found that at 55mph I was at about 2500 to 2600 rpms. With my tire size, this should put me somewhere in the 4.27 gearing range if I'm not mistaken. So i suppose I was wrong when I said that I felt like it was whining out at 55-60.

I'm in 2wd high, but I wonder if it might be "stuck" or locked in low. Somehow, it being in low seems very possible. I should have the tach in tomorrow, But since my good ol death wobble started back up agian, I've been tackling that. Priorities I suppose...

Thanks for the great ideas guys. As an update, I got paid this morning so I ran to autozone and got a small aftermarket tach (and a bucket of bondo :)) also, I compared my speed to a good gps and one of those useless police mph signs, and found that my speedo is spot on + or - 2 mph. Also, I crawled up under her and never found a tag. I did find a rivet where it seems one should be. And yes, my top speed is around 55-60. I can shift easily into 5th at 30mph.

Hello everyone, I just purchased my mj not very long ago. Got it as a "running project" from a gentleman who seemed to really want/need it gone. My question is when I try to drive on a road with a higher speed (55+ mph) the jeep seems to run out of gearing in 5th at 50mph. I can hear it really whining out, plus the idiot shift light comes on at about 44-45 mph. Also, I bought the jeep with the front axle out of it, laying in the bed because the yoke has a ear snapped off. So I've been driving it for the last few months in 2wd, and haven't tried putting the axle in, out of fear the the front axles gearing is different then the rear. What do you guys think? What would be your next step if you were me?Any input would be wonderful. 1988 jeep mj 5speed 4.0 31inch all terrains 190xxx miles
