I know the brake issues are aggravating. Wonder if it's something either with the booster or the proportioning valve?
I don't think so Joe. My understanding of a brake booster is that if it doesn't leak vacuum, it's good. I don't think there is much that can go wrong with a proportioning valve either unless the valve inside sticks to one side in which case the brake light will stay on and no fluid will pass to the rear. I am getting braking back there and they bled normally.I know the brake issues are aggravating. Wonder if it's something either with the booster or the proportioning valve?
I'd bet if you had the driveshaft balanced the vibration would go away. It's spinning faster than it was before.Update:
Never mentioned this either but I felt a balance issue with the driveshaft in this car after I had it cut by a shop in order for it to fit the 4L60E when I put it in 20 years ago. Felt fine at first but when I changed the original 2.41 gears to 3.42 not long after, I did feel a vibration. Not bad enough to do anything about since it was only felt on the highway and I didn't do that much highway driving with it.
Forward the clock and the vibration felt worse after my suspension and wheel upgrades. So, a few days ago I replaced the original u-joints (did have some visual wear) to a new set of Spicer. Well, that made the vibration feel even worse! Don't know why but I decided now I have to deal with this issue.
This morning I ordered a new custom driveshaft and a new slip yoke. New u-joints again because I want it all balanced as a unit before it's shipped. I bought grease-able ones and he much prefers using the non grease-able ones anyway. Oh well another $40 down the drain.
I would hope so. Since it's totally noiseless and not felt until 50 MPH, I just don't think it would be anything else. Going up from 50, it's a gradual increase in vibration and when I get to 75, I'd say it becomes severe. If I put it up on jack stands take the rear wheels off and bolt the drums tight to the axles, it does exactly the same thing.I'd bet if you had the driveshaft balanced the vibration would go away.

Thanks for the compliment Dan!Hi,
Been following the posting and project. Amazed at your knowledge, skill and resources you have. I was hoping you would choose the color white,
Since I live in Texas I was wondering if you could share you truck interior guy? I live in the DFW area. I have a bone stock 86 el camino choo choo in grey with grey buckets and its tired. I’ll take a different route and have to pay to get it updated. I don’t have the time, talent to do it myself. But boy I took some notes! Love to see your truck some day - not sure what region you live in.
Looking forward to the completion, that is if we ever do complete these projects, Thank you, Dan
