Tires and 4 wheel drive
Firestone sold me 2 new front end tires and from the get go I noticed
shaking in the steering wheel and significant increase in road noise. I went
back and my tech said the differential was going bad. In checking with a
company who repairs these parts when I mentioned that I had two new but
different mfg tires he immediately said that "When you replace tires you
replace all 4 because the what the 4 wheel drive on this Jeep works. Can
you validate this for me because the problem started after the new tires
were balanced, alignment done etc. If so how do I prove this was the cause
of the issues in the 4 wheel drive system? This is going to cost over $1600
plus cost of replacing 2 older tires that are in good condition.
