I have a 2000 TJ that has a vibration around 60-70 mph that comes and
goes.

The dealer inspected and I have metal in the oil and they recommend new
rear-end bearings in a rebuild of the Dana 35 rear end for $800.00

Anyone run into this, and is what is the going rate on putting new
bearings in?

Is it worth replacing the rear end with a Dana 44?

I recently put on alloy canyon wheels and 30" tires and ditched the
P195 75 R15 steel wheels

How do I know what the ratio is? I have a 3 speed automatic....

Hi Tom,
Don't throw good money after bad: http://www.billhughes.com/dana35c/
Give the bone yards a look for a TJ with a Dana 44, other places to
look: http://www.jeeptech.com/axle/d44.html and:

Hi Tom. Did the vibration stop when you let off the accelerator at this
speed, and then continue when you reapplied the accelerator? Did you
feel it through the steering wheel? Just wondering, I believe I may
have the same problem. Mine is on and off also at highway speed.

Thanks,

The vibration seems to continue even if I let off the accelerator, it's
like this vibration (2 second pause) vibration (2 second pause)
vibration

Can't feel it in the sterring wheel...

From my engineering days that sounds like two vibrations, slightly out of
phase, that alternately reinforce and cancel each other. Tires can do this,
axle bearings, carrier bearings, drive shaft, almost anything in fact. You
can replace carrier bearings yourself if you have a bearing puller
(rentable), a brass drift and a dial gauge (rentable). I don't know if I
would recommend it unless you do a lot of mechanical repairs though.
