Rear end grinding noise 68 Shelby GT500

  That's because she thought you wanted phone sex Doug. You mentioned ''rear end'' and she hung up! Simple mistake. If you said differential she'd have bilked you out of ten bucks.

Well they don't call me DD for nothing? Actually my screen name in porn was Dug U. Deeply.

Where are my boots when I need them?  It's getting deep here!   As for Randy, gone in 60 seconds has NOTHING to do with the infamous film with Nicolas Cage. LOL

If the noise doesn't go away on its own, you may have to jack up the rear of the car and pull the '63 Corvette out, that you ran over, manually. Sometimes its a 50/50 chance that they loosen up and fly out into the ditch on their own......

Almost as bad a people that lock threads to avoid the embarrassing truth.. not mentioning any names.

I know I am not welcome. I am helping two people with the wiring issues. After I walk them through I'm done. 
I know another who thought I'd be stupid enough to provide my home address to send me something out of the blue.. Ahh, a random act of kindness. Not likely. You can always tell a liberal.  Zero integrity and always a double standard.

   Every once in a while we veer off target for a reply or two . We usually come back to our normal helpful selves. I suppose we could save the "joking" for PMs but I was hoping we could share some levity in public. If something directed at me was censored , PM me so I can laugh too.
    In the time we have spent "beating around the bush" , the diff could have been pulled , fixed , and replaced , regardless of how much damage was present.
     I remain curious as to the actual cause.

Randy- I think most on here understand your mechanical abilities and your willingness to help. A few want to wander aimlessly thru the woods without any direction. Instead of just taking positive help from people that know and understand certain things, whether it be a virus, or a 3rd member that needs some help, some should just heed the advise and would probably already on their way to a better situation.

   Thank you for the kind words. I was factory trained in 1968 to do Ford differentials and unless I tell people that , there is little chance of them knowing. I've fixed hundreds of broken traction lock cases , spun bearings on early Detroit Lockers in that time and when the OP said what the symptoms were , I "offered up". Boy do I miss the popcorn emoji!

Randy and I have exchanged PMs and we even have mutual friends. ( Steve Long amongst others from the heyday of racing and the performance industry.) Cutting up should not be an issue and I am absolutely sure Randy would have got a chuckle out of it.
As for the Virus: Stay home. You can wander out when they drop. Then again, I would venture 70% here are in the age that is most threatened, not worse than the H1N1.  No, I am not minimizing it. However, I don't exist in a panic. I do what I can. 
The only thing I stocked up on is Hirtenberger high-pressure 9MM for my MP5 SD.  The "natives" tend to act up when they can exploit situations and riot. I was on the job in '92 when that went down.  I'll pass on being a victim.

Well, I am now in the same boat as you, My 66 GT350 mentioned above still has the horrid vibration and noise over 60mph, Had a pretty thorough rear end rebuild about 200 miles ago. New Ring and Pinion, new limited slip. Axle bearings, axle seals. Looks like its going back to the builder for a look see.

Cheers. Petre

Peter: Driveshaft balance, angle perhaps? Bad U-joint?

[pmustang]

Well.......pinion angle was my issue.

Unfortunately it cost me plenty to find that out but thats car. Expensive haul either way to the specialist

So I am probably going to pull the T5 and put in a Toploader (the original T10 is on the shelf)

I would love to improve the pinion angle but the tail of the T5 needs to go up and there is no room for it to go up on my car. Bit of a bummer.

Good luck to the OP with their issue.
