Got a 1986 Comanche replaced the u-joints in rear drive line and still get a road vibration at highway speeds and i noticed that i got about 1''-2'' slop on the pinon into the axle should i look at a axle rebuild?
ok thanks for the help no slipping of the pinion in or out just while turning.ok thanks for the help no slipping of the pinion in or out just while turning.

You're getting 1-2 inches of movement? Is this the pinion shaft sliding in and out of the housing? If yes stop driving it. I had a '64 corvette in my younger days. I banged second gear at 4500 rpm on nice spring day. Just going through the gears easy like. The pinion shaft broke, the pinion fell down and locked up the rear end and I went spinning in circles. Fortunately a wide road and no other traffic. I survived. If your third member locks up you may not! Talk about totally out of control! Do something about it yesterday!
If you have that much play in the pinion, your pinion is getting worn, or the nut is loose. You may be able to find a rear end at an auto wrecker cheaper than anything.

I would suggest that you check the wheel bearings for condition and adjustment
have the cv joints checked for that drive axle
check all suspension ball joints and steering ball joints on that side
If a hub bearing was bad, it almost always would make noise, more so when changing lanes at higher speed. Outer CV joints make a loud low pitched rattle when turning (corners). Inner CV joints raise hell at high speed- bad shake! Sway links affect cornering and clunk when hitting rough patches of road surface.
Is the vibration worse at 65 than at 50? If so, you are dealing with a wheel balance situation. Find an old time front end shop that will check the balance on the vehicle. You will have to turn off the traction control to do this or use an on-the-car wheel balancer.
If you feel it at some low speeds at it comes back at other higher speeds, then you are dealing with tire roundness. Possible more than 1. More common than we would like.
A two wheel drive ranger does not have any c.v. Joints.
It does have u joints in the rear drive shaft. Worn out u joints can cause vibrations at highway speeds, squeezing noises at low speeds, and in some cases a clunking noise when the transmiissin is placed in park or drive.
You can check them by pulling the drive shaft and ratting the joint. If it is stiff or loose than they are likely bad.
Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!
Check engine mounts. If it is a rear wheel drive or 4 wheel drive- inspect driveshaft(s) for damage or missing weights. Also check universal joints for wear, and the rear driveshaft slipyoke for leaks and wear. If there is a leak, the rear seal and bushing should be replaced.
If front wheel drive, inspect drive axles for damage, and inspect the steering components for damage or wear.
This type of vibration is typically caused by a bad universal joint on the drive line. I've seen a case where a bad u-joint caused the transfer case to crack and explode. Replace all the u-joints on the front and rear drive lines. They are usually only around 15 bucks each at NAPA and will be much cheaper than another T-case.
on both my Camrys, i had this problem. You could really notice it when you were driving down the road going 40-60 mph and punch the gas - car would vibrate, let off the gas - vibration stops, punch the gas - car vibrates...... On both, it was the CV joints. It is much easier to just replace the drive axles (with the new cv joints and boots already installed). For my last replacement, i think thy were only around $65 each.
As for your shaking at highway speeds, providing your tires have been balanced properly, it's probably a u-joint. If you let off the gas when it's vibrating, and the vibration quits immediatly, it's a u-joint. If it doesn't, it's a tire or wheel.
The squeak is probably a shock, but that would be a guess.
try checking your bearings on both sides. as for your brakes when you change your rotors try changing both of them as well as your pads. i had the same problems and that fixed it. if it persists i would look at your ball joints and then your calipers. good luck.
