Rear Shocks on a truck should last between 50,000 miles to 100,000 miles before they need replacing.
So that is between 5 to 10 years that rear shocks should last depending on how you drive your vehicle and how many miles you drive your vehicle per year.
The more miles you drive per year and the rougher the roads you drive on the less time your rear shocks will last on your truck.
The smoother roads are less harsh on the rear shocks and they will last longer when you drive the truck on regular smooth roads.
Off road driving or just driving on rough roads causes more wear and tear on the rear shocks.
Rear Shocks on a vehicle are supposed to last between 50,000 miles to 100,000 miles.
However the actual lifespan of the shocks will depend on the types of roads you drive on also because when you drive on rough roads the rear shocks will wear out faster.
The same is true for the front shocks on the vehicle.
The rougher roads create more wear and tear on the shocks and so the up and down motion causes the shocks to wear out faster.
The smoother roads you go down the less wear and tear the shocks will have.
For most people it usually takes 8 to 10 years for their rear shocks and front shocks to wear out.
If you drive less then your rear shocks will last longer and the more you drive the faster your rear shocks will wear out.
Rear shocks should always be replaced in pairs as in both of the rear shocks should be replaced at the same time.
Your front shocks wear out as well and last between 50,000 miles to 100,000 miles before they need replacing.
