My Death Wobble started immediately after I installed a set of Coil Spring Spacers (to lift 1.75 inches). Turned out, the DW was because while changing the height, I also lowered the CASTER angle in the front end. So, to fix it, I could have purchased a set of eccentric bolts for $50+. Instead I went out and purchased a piece of 1.5 inch flat bar for $10 from OSH. I cut out 4 1.5 inch squares. Then i drilled 7/16 inch holes centerline, but close to one side (in exactly the same place) on all for squares. I then removed the lower control arm bolts, nuts and washers. I installed these square offset washers I made so the front axle would be pushed forward (to increase the Caster angle). The toe setting changed a bit, so I reset them to about 1/8 inch toe in. After driving my Jeep, I noticed there is no more DW. The steering wheel was off center, but after 3 attempts, I have that perfectly centered. I have every intension of having the alignment checked, but not till after I find the new tires I want. If anyone is interested, I can draw out and photograph the cure and send it to you.

Check for a clogged catalytic conveter or weak fuel pump. Remove the O2 sensor so exhaust can flow out hole and test drive it. If it's better replace the cat or look for kinked or dented section of the exhaust. If it didn't help, have the fuel pressure tested as well as the ignition advance and timing chain.

TRY TO TIGHTEN THE PCM CONNECTORS UNDER THE HOOD ON THE PASSENGER SIDE FIREWALL. COULD BE A BAD CONNECTION. THERE ARE THREE LARGE WIRE CONNECTORS GOING INTO THE COMPUTER HELD IN PLACE BY THREE BOLTS. YOU'LL NEED A 10 MM. SOCKET AND A RATCHET.HOPE THIS HELPS. GOOD LUCK

You can check fluid level by removing the rubber plug in the cover. Fluid is full when on level ground, it is just at the edge of the hole (or very close) if you are already getting noises out of there, you can remove the cover and inspect gears for wear or breakage. If you find a large amount of metal debris in the lube it tells you something bad is going on back there. Although rebuildable, it's not a home job...requires exact settings in order to operate properly. You can find good units far cheaper than even a gearset costs in any scrapyard. to match ratio, count the teeth on the ring gear and the pinion gear. the replacement MUST have the exact same number. Before swapping diffs, check all back there to make sure noise is not from somewhere else.

Check under drivers door sill step. There is a spice I believe the wires are red or pink in color. The splice will be wrapped in black hockey tape looking stuff. Peel the the hockey tape stuff off and you will find that this splice is corroded and not making contact anymore. You can repair this splice and your problems will be fixed. Be sure to use some good heat shrink on your repair to prevent from happening again.
