silly question but I don't know! How easy is it to replace the shock absorbers on my GQ patrol? Any alignment necessary or is it just a bolt off, bolt on job?

Gossy,
There a couple of things to do before the shocks can be fitted correctly.
These days shocks are normally gas shocks with oil. The shocks have to be primed before being installed. To do this remove any tie down device that is compressing the shocks. Allow the shock to expand and then compress until fully compressed. Repeat a few times. This gets any air bubbles out of the system and makes sure that the oil is at the on the lower side of the values.
It is easier to remove the wheel first to allow access to the shocks. Make sure that the axle is supported by axle stands. Remove the old shock and then insert the top of the shock into the top mount. The shock is going to be a lot longer than the space between the top and bottom shock mounts. The shock will have to be compressed to get it to fit.
Make sure that the bushes are fitted before the pin is placed into the shock mount. Fit the other bushes and tighten the nuts, but don't over tighten, the instructions that come with the shocks will say how tight they should be.
The rear shocks would have a lower eye. This also will take some effort to line up and slip on.
After that replace the wheels remove the axle stands and drive away.

Wayne..the old twin tube oil shocks needed to be primed to make sure the oil was air free, but now with gas or foam cell shocks the oil and gas are separated by the floating piston in the base of the mono tube and never come in contact or they are buggered!
No need to prime!!

I agree with most of what others say. However, they can sometimes be a bit stubborn for rubber or urethane bushes to slip off/on the eyes bolts - just spray some soapy water on 'em or spit on 'em and they slide in like a,,,,,,,
well you know ;)

I have done some that are easy as undo the 2 bolts and way you go. Others way have as
well been welded on hammers chisels etc etc. Had to go to a mechanic with one pair once who spent a good amount of time with an oxy.
try taking the old ones off - if it is easy it will only take a few minutes. If not get the quote for fitting written - coz as said they can tke you alot longer than $100 of your time if things go bad

Hows it going ,
I initially fitted Rachos to my GU , the urathane bushes on the back were a real pain to fit even when greased.
When they needed replacement I started with the hardest one , back rh , and finally folded , went back to the place that I bought my new shocks from and got them to do it , at least it was worth it to see their apprentice struggle to get the old ones off even with the car on the lift.
If it happens easy , you save a hundred , but if its a PITA is a hundred worth a whole day under the car angry ?
