OK, so I’m new to the forum for a second time due to being over sees for several years with the military. I am having a problem with my new mustang. It has a vibration at 70 mph to about 80 and as soon as I push in the clutch to change gears it makes a loud wining noise with every gear change. It’s a 92 GT with a 306, tremec 3550, aluminum drive shaft, 3.55, 5 lug conversion, and is lowered,245/r18 in the frontand 285/r18 in the back. There are other modifications but I don’t think they play into my problem. I recently had the tires balanced and it helped but it is still there. Any help would be helpful.
Thanks, Chris

I'm gonna have to lean towards your rear gears. Not sure how old they are. Maybe they were installed improperly. Hopefully you get more replies. Good luck

I had a similar problem once, it turned out to be worn U-Joints.

Yea I am going to check my u-joints now. I checked the wear on my gears and they looked good, and the wining is coming from the trans.

First, I'd clock the driveshaft 180*, if that doesn't fix it I'd then check the U-joints, then have the gears in the rear end replaced by a reputable shop.

then jack your car up and suspend the rear end and try it in place, with the wheels on, if you still feel the vibration, then take the wheels off. I had a problem like this and it turned out to be a bad wheel, but i had my driveshaft ballanced, changed u jonins, had pion angle checked, then I jacked the car up and did what I recomended to you.

make sure you have a buddy there it will give you a good chance to see what is going on.
