Finally, finally it is done.
Installed a 4.10 ford 8.8 and all new brake hardware.
Installed a 4.10 D30 from an 87 XJ, but used the axles/hubs/brakes/knuckles from my 90 XJ
Installed Rusty's 6.5" long arm kit
new u joints in axles, new u joints in driveshafts (front is stock, rear is 95 grand cherokee front shaft with CV)
Installed SYE in 'spare' 242 tcase
Installed new tranny mount
Adjusted steering
Adjusted pinion/caster angles
Just COULD NOT GET RID OF THIS FREAKING HUMMM/GROWL/VIBE.
Checked/double/triple checked u joints and driveshaft angles - they were good.
all wheel bearings appeared good during the axle installs but jacked each one up and spun the wheel - no significant noises, no wobble (the 8.8 bearings are apparently slightly loose from the get go)
test drive, listen, test drive, take out 1 driveshaft, test drive, take out other driveshaft, test drive, listening - trying to find where this noise is coming from.
couple friends come for test drive - concensus is the noise is rhythmic at wheel speed so drive shafts/tcase/tranny eliminated.
down to wheel or carrier bearings.
start at the rear and do the PS wheel bearing. no love
do the DS rear wheel bearing. no love
PS front wheel bearing (new hub unit) no love.
hmmmmm.. running out of options here.... do the DS front wheel bearing and immediately upon removing it, it was obvious there was a problem
UN-freakin-REAL!! it definitely had a bad tight spot but couldn't feel/hear it while on the vehicle.
replaced it with the one I removed from the PS and Hallelulejah!!! we are ready to go wheelin!
This is not my quote, but it is accurate - "if it quacks like a wheel bearing, it probably is a wheel bearing"
