Last summer the drivers side rear lower control arm broke. Since the year before I rebuilt the whole front end I figured it was time to the rear. I ordered 2 lower control arms, upper control arm, rear springs and shocks. Naturally all of the parts did not come in at the same time. With the parts I got I changed out the broken control arm, both springs, and shocks. After doing that everything worked fine.
Then the other lower and upper arms arrived. I replaced both of those. Now while driving it I get an intense vibration that had been happening between 35 - 45 mpg and 1200 to 1500 rpm.
I double checked myself and torqued all of the bolts again while it was on the ground (not easy to do). No help on that one.
One thing I did not get right was installing the exhaust again. The rusted studs needed a few washers to tighten it. It was still loose on the first attempt so I took it back off and added another washer to space out the nut. That got it tight but had the undesirable affect a changing when the vibration happens. It now happens between 40-50 mph and 1500 to 1800 rpm.
Researching the issue here lead me to a number of posts that point to the universal joints as the issue. They are cheap so I just bought 2 new ones planning on changing them in a few weeks. Well its now a few months on and I finally took the drive shaft off. The existing universal joints are free with no apparent wear on them. I did not change them. They don't seem to be the issue.
Any other ideas on what might cause this.
