To replace rear shocks on your vehicle it takes between 30 minutes to an hour depending on how easy it is to get to your rear shocks.
If your rear shocks are easy to get to such as on a truck then you can replace the rear shocks in less than an hours of time.
I replaced the rear shocks on my truck last year and it took me around 40 minutes as in it took me 20 minutes each side.
However sometimes you might run into problems such as the bolts being stuck which can make it take longer.
A shop can usually replace the rear shocks within an hour or less.
On cars and other vehicles where the shocks are harder to get too it could take a few hours to replace 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.
