yes only while moving and vibrated worse the faster I went . I was only going about 15 mph bc it was so bad . would the air ride suspension have maybe caused this bearing to go bad ?

Center carrier bearing or losing a u-joint...better crawl underneath and take a look!

Check your fan first. Old fans do break and send a fan blade flying. The resulting vibration is hard to believe. Been there, had that happen.

The worn out u-joint or bearing that you have been listening to go clunk ever time you put the car in gear for as long as you can remember has probably now given up the ghost entirely.
Remove the driveshaft and renew all of the consumable parts.

A few suggestions prior to 'guessing' and throwing money at the problem:

Look under the car for obvious problems.

Sitting still, in neutral; rev the engine. Hear your noise? If so, the problem is NOT in the drive train, nor the suspension.

When driving and making the 'noise', does putting the car in neutral (and coasting) make it stop? If so, it's likely in the drive train; not suspension.

Allow the car to roll down a hill (in neutral, engine running or not) and get up to the speed the 'noise' typically appears. Hear 'noise'? If yes, it's not torque related, it's speed related (suspension).

Another 'test' for 'speed' vs 'torque' causation; as the car is allowed to coast 'faster', does the 'noise' increase in frequency? If so, suspension needs a thorough inspection.

The proper drive train angles, and how to measure them, are in the 61 Shop Manual. Check 'should be' vs what you have. If you are significantly 'off', you are putting more stress on the drive train parts.

All 'free' inspections/tests.

In summary, find the problem THEN correct it.

While coasting in neutral with engine running or not, the driveshaft is turning and if it’s a bad center bearing, it will likely be banging.

You're right. The rear gears will rotate it as the wheels rotate. I know that. My bad.

I’d check carrier bearing and U-Joint. I’d get the HD carrier bearing and slip yoke.

not yet. but from what I'm reading and being told it sounds like the drive shaft / carrier bearing . its never been replaced as far as I know, and I've had the car 20 years now . but I will do the tests people on here have mentioned doing tomorrow or Monday. I keep my car in my parents garage an hour away so I can't really get to it during the week . someone said pull on the drive shaft back and forth and see if there's alot of play ?

for some reason your post just now showed up . for me at least. so since I have the money would I be better off to just get a slip yoke shaft with a polly carrier bearing? do i need a whole drive shaft or just the rear section?

Since I was changing to a 700r4, I had my driveshaft shortened and the slip joint added by a drive shaft shop. They were smart and insisted on having one of their guys come out and take measurements. I bet that saves a lot of grief all around.

Anyways, this is what is looks like:

Since you had no issues until now just pull the drive shaft and have a shop replace the u joints and carrier bearing and balance it and put it back in.

You don't need a slip joint shaft if you havent had any other issues.

copy that. do you know of a video that shows how to remove it? or is it simply just removing a few bolts and it slides out ?

Take the 4 nuts off of the drive shaft universal U bolts, unbolt the carrier bearing, push the driveshaft forward a little bit, and lower it. Then pull it out from under the car. Put a drain pan under the end of the transmission to catch the oil or gear lube. Should take you more than a half hour to remove it. If you can get a plastic plug from a transmission shop, you can plug the end of the transmission to stop the loss of the oil. Takes a second person to do this.. one pulls the driveshaft forward, and the other one quickly puts the plug into the tail shaft.
While this isn't specifically for your car, it will give you needed guidance to do the job successfully.

Once out take it to a local drive shaft shop. They are equipped to do it right.

I bought my slip yoke from Inland Drive Line and I think the HD bearing too. I did all my driveline in my garage with C-Clamps. If you got bags I’d get a slip yoke and if your frame isn’t all painted and pretty you could trim the center of the frame some where the driveline comes out to help prevent binding if you have a higher lock up.

since its making the clunking sound when putting into drive or reverse do i need to replace the u joints at the part of the shaft that goes into the transmission? or would a slip yoke shaft/new carrier bearing take care of everything?

You’d have to pull it out to find out what’s wrong, could just be the center bearing is shot and when you put it in gear, the “load” on the driveshaft torques it sideways. Other than the leaking transmission fluid is a pain/mess potentially, if you jack the car up and put it on 4 stands, it pulls out real easy. 2 nuts on the back end, 2 bolts on the bottom of the x frame that screw into the base of the center bearing. Then just push it hard forward until the driveshaft drops out of the rear pinion. Pull hard backwards and out it comes. It’s max a 30 minute job and not complicated at all. 9/16 bolts in the center and 7/16 or 1/2 on the rear at the pinion.

I wouldn’t bother with the rear shaft upgrade or the poly center bearing, unless you are a low rider or have 400-500 hp and go drag racing. Keep it simple.
