No spacers, wheels are straight springs are good.One thing that did happen a couple of months ago.I got a flat tire and had to patch the tube. Could this have something to do with whats going on now? Could it be something internally in the rear end causing the issue with tire wear and vibration?
Thanks for the input.


Yes, most definitely it could. I'd have that tire rechecked for balance and make sure the tube is installed correctly. I'm surprised you have tubes, that's rare now days.

Also, is the vibration only at a certain speed or constant?

And, when you feel the vibration, to isolate it, try kicking it in neutral and see if the vibration goes away when you're coasting and the drive train is not under load.

Have you checked pinion angle..? And also drive shaft yoke not being deep enough into tail shaft over time can cause vibration as it wears prematurely.

Sorry, I didn't read the entire thread, so some of these may have already been suggested.

Regardless, best of luck locating the source.

Thanks guy's.Will post back with what i find out.
Hate to keep harping on the shock absorber....However, I'd remove the shock and check for proper operation just so it can be eliminated.
 
Will do POPS.Can you explain, how the shock being bad would cause the tire to wear out on the inside of the tire?
I positively know it will on the front, because I just had to change a set of shock/struts on my 2009 Silverado, because the left tire was cupping on the inside and causing a vibration....I actually thought I had a wheel bearing going bad, when I first noticed the noise....I may be comparing apples with oranges Jim....But, based on this experience and what happened with my 72 Nova years ago, it just waves a red flag for me.....I must admit though, I don't remember if the rear shock problem caused a tire wear problem on the Nova or not....However, I do remember it caused an annoying rear vibration issue.

Please see this about cupped tires:http://blog.nwautos.com/2009/05/cupped_tires_are_real_--_and_a_real_danger.html

"There are two main causes of cupping. One is an inadequate suspension system. If your shocks are worn out and the tires are literally bouncing up and down as you drive down the road, every time they come down, they get scuffed, and that leads to cupping."
 
According to the picture of your great looker it looks like you have 10'' wheels? How do you do that without narrowing the rear? Any way check your axle bearing by supporting the rear and lifting the tire with a pry bar the same way you would a front ball joint looking for up and down play.A rear drum can be out of balance also

Thanks POPS for that info.I will be checking the shocks.My back has got me down for a few days.I just had a few injections in my neck,so that will be ok for awhile.Lower back gets me down now and then, then is here now.
Thanks.

I did a mini tub, springs are moved to the inside and i'm using a s10 rear end that is 54.5", don't to narrow it.I will tearing it down and checking things out.As soon as my back lets up some.
Thanks for your input.
 
Ok couldn't wait, the shock is good and it should be it has maybe 7k miles on it.
I too k a video, take a listen.Also there is side to side play in the axle bearing, how much is to much side play.And it sounds noisy in the differential also.
Sorry, but I don't think that's just a axle bearing. A little more serious than that. I've never seen a rear end coast that much. Must not be any pinion bearing torque.

the axle should move side to side no more than .050" from the video you have a differential problem. either pinion or carrier bearings or both or an exploded gov- lock unit. time to pull the cove and see what mess you have inside.
 
It definitely sounds like a rear end issue to me and I agree with Don that sure seems lik a lot of free spinning when you let go of the hub and I have never seen that either. Was your drive shaft disconnected when you filmed that? No pun intended but it sounded like the Wheel of Fortune wheel when it was spinning freely. My suggestion is to pull the 3rd member and take it to a R&P shop for a diagnosis, good luck and hope you find the problem.

Just realized you have an S10 rear end, I would still take I to the shop though, good luck Jim,

Most Definitely.. Was the wheel re-balanced after the repair?
Did you drive on it flat. The extra grams of the patch can transpose into a vibration, As far as inside tyre wear, Was and is the wear near the repair area??
If so you may have damaged the sidewalls of said tyre or caused a fracture in the steel belts causing separation..
This will indeed cause a major vibration..
CHECK THE TYRE..

No didn't drive on the flat, wear is not near the patch area,tire was checked twice for balance, spin balance and a road force balance machine, and it's bias ply tire not a radial.
Thanks
 
One thing for certain Jim, all that noise has nothing to do with a tire or shock, that is definitely something to do with your gears in your rear housing. and man, that sure spun a long while, especially with the driveshaft connected...

Best of luck :tu

Let us know what you figure out...:tu

Ok, i believe it spun so long was because there was a wheel and tire on the other side.Also it is not a posi.Plus all the oil was drained out.But just looking at everything i don't understand where all the noise came from.
I have pulled it all out, and there is nothing broken or any metal pieces.The only thing i see is some wear on the axle at the axle bearing area,which looks to be minor.The noise is coming from the gears when you spin it, should the gear lube sort of deaden this?Ring and pinion gears look just fine So, what i'm going to do is replace the differential and axle bearings,and replace the spider and differential gears if that is what they are called.Pinion bearing i see no issue with it.Anyone who has more to input please do, i have never really messed around with r/ends except for my first car in high school which was a 55 with a 4sp and a 327.I went to the junk yard several different times getting spider gears.I miss that car, had a lot of fun with it.
