2005 Honda CR-V vibration on sharp turns

Customer complained about a noise and or shuttering when turning into a tight parking spot. The shudder is there everytime but only on sharp turns at slow speeds. The CR-V only has 52,000 miles on it.

SHop:
test drove and could duplicate the exact issue as described by the customer. Pulled into shop and put up on rack for further inspection. The vibration is in fact coming from the rear differential. With the engine off and holding one tire still and turning the other tire slowly you can reproduce the vibration and watch the rear differential jump around.

All research points to changing the differential fluid and Making certain to use Honda Dual Pump Fluid Only! According to the operaters manual the differential fluid is due to be changed at 60,000 miles. Unit holds 1.3 qts of fluid.

FIX:
Drained and replaced fluid with Honda Dual Pump Fluid II, that I got at my local auto parts store, and test Drove. Problem solved.

Jeep Liberty rear end trouble

Have you heard of blowing your rear end due to driving with a different tire. I had put my spare tire on 3 days earlier due to a flat that could not be repaired, the spare was an all season, other 3 are mud and snow. The wheel base was the same, just 1.5 inches difference to wear and tare on tires and different type. (I was waiting for a replacement tire that was on order.) The mechanic at chrysler is telling me this is the reason the back end went. (Too top it off, my mileage is at 102,000 and the warranty was to 100,000.)

Now that i have my new tire, the mechanic says it is still 1/2 larger and the other tires should be replaced . Is it possible to blow the rear end again?…or is the mechanic covering his warranty by telling me this is the cause of the rear diff major damage…r/r complete assembly Replaced.
