Sorry to rehash a lot of the same that's been covered already, but needing some guidance on a few of many issues still needing attention on my 89'. First off is the drive line vibration. I have followed many threads with different outcomes, or lack of thereof... and would appreciate some starting points without ripping car apart from end to end in the process. I'm getting a gyrating vibration, that seems to be inconsistent depending on what day it is. It starts around the high 2k range and seems to progress through 3k and up getting worse, but like I said not always consistently. You can feel the oscillations through the shifter rather intensely at higher r's shifting, both under power and deceleration... makes for lousy highway driving with the 4.10's to say the least. Replaced the trans mount, checked u-joints, and starting to think it's centralized in the trans or clutch as I'm sure if the tailshaft were bent it would destroy the seal and leak seeing as how badly the vibe can get. So starting to think clutch, but wouldn't issues with pressure plate and/or disk pretty much also show major slippage and erratic shifting issues? Just wondering if anyone had any ideas that could help save me tearing entire driveline out and replacing pieces at random. I'm certain it's isolated between engine and trans somewhere. Sort of feels like a pressure plate with missing bolt heads almost, but not sure if it would even shift if that were the case. Also having issues regarding ignition switch. Replaced not all that long ago, but it seems theres something not adjusted properly or perhaps bad contacts somewhere. I get a gnashing noise every time I start the car that almost sounds like the starter is not disengaging soon enough, also the switch detents seem weak at best and takes a little wiggling to get the key position in the right spot to avoid kill etc.... It was working fine for quite awhile, but I remember when I first replaced it was giving some headaches with movement after setting etc(and this is the 2nd time replacing). Another not so critical issue is after fixing the numerous wiring issues and replacing computer, the CEL has not lit for quite some time. Today was the 1st trip on freeway as I drove it to work, all other driving has been in town. Halfway to work(25 mi trip) on comes the light just like in the past when I had the wiring issues (inc. a bad ground in the A9L)....replaced and traced all wiring problems and repaired(per Jrickters diags), hoping this issue was over, but here we go again. Frustrating because I need the car atm for DD duty...
Thanks for any suggestions...
