Well, after the tire change, car running good......... then on a pleasure cruise for abour 35 miles to my destination. 25 miles in, back end vibration came back home to roost. I was goung 55 to 65 on the trip. Had to pyll over. Now, im not the type to lose my temper, throw tools, or hv tantrums, but im gettin to my wits end on this. After i pulked over, i felt the hubcake, not overly hot. So i decided to drive on at about 40, as i got miving i pushed on up to 55, not one vibration. So, wtf coukd it possibly be from here.
I have had.....
Changed cylinder.... twice! First new one was stuck!
Axle gasket replaced
Had drums re cut,
I sympathize. I jus got a 1964 sedan deville and had the same issue. I'd get it up to 50MPH and a low frequency vibration would start. It would grow until I could see the hood bouncing. I had to pull over to make it stop. I tried a bunch of things but believe it was a front brake adjustment that fixed it (so far). I had over adjusted the front drums and after they got hot the vibration would start.
Yes. Very frustrating. I woukd go out for ride w big smile. 15 min later was turning around....pissed. i think brakes are fixed. Other than that last episode of rear shake, last couple rides hv been ok. Just tge uncertainity of a pitential problem sitting in wait. You kno the potential is tgere, just waiting on it to rise at most in opprtune time, like on a hot date (well,as hot as a date can be being over 55). Heres hoping for best
It is interesting that you describe the kind of shaking and vibration you explain and relate it to a front brake issue
I had the same kind of vibration but only when i was coming to a stop from 10 miles an hour and below every time i would hit the brakes --to stop
Not at 50 MPH
A very Violent shanking of the front end
My problem was brake shoe related
The brake shoe friction material was not able to handle the heat generated by our large drum brakes and where glazing and cracking the shoes
My shop gave me back my car doing this after having my front brakes and the entire car gone over from one end to another
It took me a long time to work thru this problem --as new part were just installed and NOT thought to be the problem for that reason
Sounds like a similar problem at very different speeds
New defective parts -present a new set of problems when working thru an issue
The new part are --least suspect as they are new
Kim --just went thru this with a bad new brake cylinder that was causing his rear brakes to hang up -over heat and drag on him
Took a while to work thu that for the same reasons
I would do one thing at a time
You did the grease in the U joints - so test to see if the problem does not return rather than throwing parts at the problem
The grease should tighten up any slack in the U joint caps which might help this
When and if the problem resurfaces i would do the new rear control arm bushings and then the driveshaft inspection -or the other way around
A plan for the future if needed
As the Italians say in NY -- " FORGETABOUT IT !!!!! " ( until it returns --- ) --LOL !!!!
The very up side of this is ---that when you do finally get all things corrected and repaired ---that will pop up --there will be a very long period of time just enjoying the fruits of your labor and the joy of owning and driving the car
There is a light at the end of the( greasy ) tunnel !!!
That is --UNLESS you spend so much time --Test Driving - the car that you wear it out and need a complete drivetrain rebuild ---PMSL !!
