It SEEMED to get progressively worse on my 2300 mile trip for IZ XI.
99 Interstate. 42K on the ticker. I have disassembled it all, and everything SEEMS to be great. The splines are greased and in good shape. I pulled the rear end, and the driveshaft splines are pristine. I pulled the u-joint, and it seems good to go too.
I only notice it when I feather the throttle to make the driveline TOTALLY slack. If I am accellerating or decellerating the vibration is not noticeable. I feel it, not hear it.
I rode my Standard today, and confirmed that it's NOT a feature that I just never noticed before. The STD does not do it at all.
Anyone got a thought?
I am going to order new O-rings and lube everything up and put it back together unless someone stops me.
I had it apart about 9K ago, when I went dark-side with it and I did the spline lube then. I have changed the final drive fluid as well, with RedLine synthetic lube.
I am stumped. I have never even HEARD of any transmission issues.
It couldn't be wheel bearings could it?

My first thought reading was wheel bearings, and I was looking for those words through out, that you have already looked at them.

I couldn't TELL for sure.
I'll inspect them a little harder after some pizza.

search about the wheel dampeners.

I cannot detect anything wrong with the wheel bearings. They seem silky to me.
Wheel dampeners huh?

When you say driveshaft splines does that include the pinion cup?

I can't figure out how to get it apart. I have not fully researched it yet... but I can't seem to get it apart. I can't even get to the "nut" that people in the archives seem to be talking about that you suggest an impact wrench to loosen.
Bear with me... I have never been into one before. I am a passible, if slow, mechanic.
I removed the "ring" with the O-Ring on it. But then what?

I did, but I never got any.
I wasn't being smart about the spelling. Just a hypothetical... "Wheel Dampers huh?" Just a head scratch.
I looked into it some. They seem OK.
I am still baffled. Once I get the pinion cup apart, I'll have inspected everything I think.
I dunno...

U-joint. Check it real close, I think you will find that there is a very small amount of play, especially in one plane or direction. I had just what you described like when you slack off as you go over an overpass. I found that small amount of play and also replaced the drive wheel dampers which had some play also. Problem solved.

While you have it off it would be nuts to put it back together without getting the drive shaft off and looking at the pinion cup. Slop in the dampers maybe however my guess is left bearing or pinion cup.

Put towel down to cushion pumpkin if you drop it. Hold up rear end BY the shaft, just slightly over the towel, so the entire weight is supported by the shaft. Tap the side of the pinion cup with a hammer or such. Should eventually pop apart. If not, maybe corroded, inject some lube by the seal...wd40 or something and repeat till works. |

It is the slop between the output shaft and the drive shaft splines allowing the u-joint to get a little out of the concentric circle it runs in.
With no force on the splines the u-joint loosens up a bit on the splines and causes the out of balance condition.
A new u-joint will correct the problem for a while, but eventually it will return.
It doesn't happen at the lower speeds where the range you cruise at but get up around 80 or more and it will happen.
It seems to be pretty common I think but some may have never experienced it, and others will fail to understand or recognize what you are even talking about.

When you check the bearings, apply some side load. In other words, while you're rotating the bearing with your fingers, also push in and pull out on the inner race. You may find they're not so smooth then. I had bearings that behaved this way, as did Rainmaker. All that said, I'm voting for a worn pinion and pinion cup. |

Take a large crescent and adjust it to fit the small diameter of the drive shaft Move the crescent down towards the ujoint end until it stops on the larger diameter. Take a heavy rubber hammer and hit the crescent up close to the shaft and drive it away from the final drive....usually dont have to hit it too hard. |
