Death Wobble Mystery

lundi 25 août 2014

2003 TJ daily driver and beach buggy with 85K miles

Went with a Rough Country 3.5 lift kit about a year and a half ago with absolutely no issues. Drove like a champ on and off road with 0 death wobble or vibration. A few weeks back out of the blue she has a psychotic episode of DW and tries to throw me to the curb. Got underneath and did the usual visual, kick, tug & pull, inspection and found some worn stuff. I replaced all front ball joints, tie rod ends, drag link ends, upgraded the track bar, checked all bearings and u joints, and replaced the rears. Also replaced the RC steering damper w/ Rancho 5000 then rotated and speed balanced the Pro Comp 31's. Now I'm noticing that in the first 10 minutes or so of driving she'll attempt to wobble at around 55. However after she warms up a bit it becomes nearly non existent. after sitting for a long while or overnight she'll do it again until she warms and then it goes away again. I've also noticed when making very slow turns, like in a parking lot, the steering wheel doesn't return to straight smoothly, it kinda stutters. Could it be my steering box or power steering pump? any assistance or other posts referencing this would be appreciated as I couldn't find any:confused:
