1965 Corvette 4 speed
When up shifting or down shifting the back end of the car gets 'loose". Tires have correct pressures. Could it be something has come loose with one of the half shafts?

Jim,
Upon inspection the shafts are tight with nothing obviously loose. Thanks for the informationComment

Re: 1965 Corvette 4 speed
I had a similar problem on my 67. The rear of the car would give a little "wiggle" when shifting. After replacing everything in the rear suspension (frame off) it still did it. John Hinckley suggested that I drive some tight figure 8's in a parking lot to "free up" the positraction clutches. Problem solved. The bottom line was "lack of use" of the car. You might have the same problem.Comment

Re: 1965 Corvette 4 speed
Owen as mentioned by another poster (Stephen L. ) using tight figure 8's to solve his problem, another maintenance area is changing your 65's rear end lubricant and installing the required supplement with the change available from GM for positraction rear ends. Your 65 may not have positraction, this was an option in 65-69 and earlier Corvettes. GM's rear end lubricant part #1052271 and GM's limited slip differential lubrication additive is #1052358.Last edited by Jim T.; July 23, 2013, 08:52 AM.Comment

Stephen,
I have just climbed out from under and could not see anything obviously loose or missing. However, this vette does not have positraction, but, it does sit for long periods of time. Thanks for the suggestionComment
