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!!

Matt.

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 guess what I am trying to workout is whether it is worth the effort and my time to do it myself or pay TJM $50 per pair to fit.

cheers,

Do it youself and gain the experience for when you have to do it in the bush in a less friendly environment than your front driveway.

Keep the old ones if any life left in them for an emergency replacement in future.

Spend the $50.00 on flowers for the wife...:-)

it's her birthday next week to (or I could spend the money saved on something for the car!). Probably not a good career move though!

If it is as simple as some elbow grease then I will do it myself. I was just a bit nervous on if there was alignment issues etc needed to be done by an expert but obviously this isn't the case.

Thanks everyone.

There is virtually nothing expert about a GQ. It is just a bush vehicle built like a truck. Take the old shocks out and fit new ones. Take the wheels off to make the job just a tad easier. Go for it.

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 ?

Glenn.

well tried it on the weekend and removed the top bolt in seconds. The bottom one was on so hard to I could not remove it. The body of the shocker would simply spin with it. Tried everything including using an oil filter strap to grip it.

So bottom line is yes it was an easy job and it turned bad so the $100 doesn't seem to bad. I will be talking to them though on not putting it on so tight again!! What if I did need to do this out bush, I would have been buggered.

Thanks everyone.

I had to cut my front ones off with the angle grinder. I tried for about 10-15 minutes with pipe wrench but to no avail. Perciverence (spelling) is the key. The rear ones were easy 2 minutes flat.

Have fun
Cheers Luke
