forgot mention to get away from the dealership and bring it to an independant shop for second opinion. dealerships often succubis.
are you using gas magnums or off road shock? are they adjustable?
rec. getting second hands on opinion. if need to be replaced, rec. off road shock(ranchos by munroe are good).
off road shocks cost a bit more but last longer and are heavy duty compared to some like a gas magnum(also by munroe) shock absorber. rancho 5000 should work just fine.
theoretically shock absorbers should last up to 2 yrs. min. possible failures increase with use of adjustable shocks or by using generic brand(cheap product).
I drive this vehicle back and forth to work on a highway M-F. I have never gone off road 4 wheeling. Can there be an engineering problem with the backend?
it is possible however more likely part failure. off road shock absorbers are just built heavier duty. if your not offroading, stands to reason they will out last some thing like a gas magnum shock. they work well on pavement and deal well with winter conditions(slush, snow, broken ice).
i can't think of any reason however that your shocks would fail three times consecutively unless they are using bottom rung brand.
rec. buying the parts yourself so you can see what u bought on the ride after install. some times cheaper to buy the parts and bring to independant shop for install. if you do bring it to another shop, ask them to save old shocks for examination. the only way to see why it failed. take prob. out the dealerships hands.
