On my way into work for a nightshift an hour ago. Noticed a shudder on flat ground driving at 40mph just above 1500 rpm. Drove another quarter mile coasting , then pressed accelerator and felt the mild shudder- hmm, coilpack I'm thinking. Another quarter mile, and I'm starting to think tranny/driveline issue and pull into parking lot. No catastrophic failure or massive grinding, but I chose to not push and find out. I sensed that if I went any further I would definitely find out in a bad way. The tranny did not slip, or no racing of rpm when I gave it gas.
After calling wife to rescue me in her 03, I did all I could in the dark to check things out. Trans fluid is fine, though smelled a good whiff of something going on and I'm guessing its a diff/trans case issue and not the tranny. Nothing falling off the truck, so no obvious signs as best I could tell in the dark in my 3 minute diagnosis, had to get to work.
Hopefully the front diff is shot and I can get an ARB! No CEL lights. After stopping and turning off truck, I restarted after a quick check and put in reverse; shudder started on engaging tranny and slight press of accelerator- in neutral there is nothing, so no engine issue.
175k on my '99 and after doing alot of various maintenance the past 6 months, the truck has never run better in my 7 years of ownership. Flushed the tranny a couple months ago, I put in a new radiator, and did all the diff fluids over the summer. The truck has been a rock until tonight. Will get under the truck in daylight tomorrow before towing to shop.
So, best educated guess with this limited info? I'm guessing I could try the front diff bypass procedure, but really don't have time or inclination at this point. Thanks for any direction you guys can provide- It will be towed tomorrow afternoon.
