I replaced my current struts with a slightly taller strut... you'll see what I mean by the before and after shots... the main reasons being to get an extra 10-15mm of ride height and also give extra clearance between the tyre and strut seat spring to allow a higher profile tyre... 215/75-R15 BFG A/Ts to be precise.

Jack the vehicle. Lower onto stand and remove wheel. Place jack under the hub pushing the strut, compressing the spring with the weight of the car allowing you to secure the spring in a compressed state so you can get it on the new strut. We used some tie wire looped 4 times and a cobb & co twitch to lock it off. Originally we just released the strut in the ground and realised our folly. So we compressed it between some firm ground and the tow bar by lowering the car down on to it, wired it up and it was easy to re-assemble the new strut. Second strut we got smart with the first solution offered here.



Remove the sliding clip that holds the brake line onto the inside of the strut. Needs just a little tap up and towards the rear. Then after holding the brake pedal to the floor using something like a broom stick remove the brake line from the rear of the hub. Just a little leakage so we bled the brakes after the job was done.


Undo the two main 19mm bolts that hold the strut to the inside of the hub. I used a solid bit of pipe to crack em.
Once we got the nuts off we left the bolts in for some support to work on the top.
Remove the top plastic cover inside the vehicle and revealing the 3 top strut bolts and nuts. I made an arrow pointing to the outside of the vehicle but there is a 'out' marked with a line so you can orientate it correctly for the re-install.
I suggest you crack the main strut nut whilst it is still in the car. Just saves a heap of hassle as its a bit of a wrestle outside the car. We used the stock Forester Wheel wrench with my old matey long pipe again.... drop the seats and swing like a mofo. At this point I'll point out that I have a strut lift so we had to remove the strut complete, remove the strut lift block and put it back in.

Instead of disconnecting the brake hose just remove the clip and cut a slot in the bracket, saves having to bleed the brakes. And i'd also recommend using spring compressors.

I dont intend having to replace a strut unless it was necessary. The replacement strut is slotted so no need to remove the brake line for the next job.

Got a set you could ship over to Perth for the weekend mate :iconwink:
The idea is to give people without specific tools the understanding that it can be done with some ingenuity and common sense. My off sider and I have worked in the rigging industry for a few years now. Our chosen method of holding the spring compressed was well and truley safe and sound. Hate ya to see what I don't publish :iconwink:
 
Well done SKT - what struts did you install? (I'm assuming in the first pic that you are removing the Excel-G)

Actually the Excel-G was the replacement strut..... cept when we did the first change we forgot the bottom vibration rubber between the spring and strut seat so we had to pull it again and do the job properly. Thus the pic of the installed new strut looking like its coming out again.
We are jets now. I can replace a strut in about 25 minutes.... I 5hit u not.
 
Ah OK - I thought it was looking too clean!
 
Excellent! So you are saying that those are custom struts from Scorpion? Did you lose any strut stroke length?


They've got KYB stamped into them so I guess they are something stock... just a guess mate.
Stroke length...???? Do you mean articulation.... if so... well its hard to say really... I didnt do any testing before hand. I do think that my right rear needs some camber adjustment though. Better sort that quick as possible I guess.

My initial idea was to get the car higher so as to take the load when going on long drives. Once the fridge and crap was loaded it pretty much sat down where I had started. I do see the rear sitting that bit higher so I'm hoping this will put me in better stead when offroading with a load onboard.
I'm still considering a stiffer spring like Kevin has gone to but awaiting some short and long term feedback of his new-ish setup....

Kevin...???
 
Yep, they look like Excel-G which we mostly use for replacement:

My 250 ft/lb rear springs did very well on the Savanna trip. They are a little harsh unladen around town - but I just drop a couple of PSI to compensate. :iconwink:

Funny thing is....I blew some dust off the old struts last night... they are Excel-G's also.... but the ones I bought def have about 15mm more space between the lower strut mounts and the bottom of the spring seat.... cant quite work it out.... I checked KYB.com and cant find any mention of different length Excel-G's.....

Any clues any one?

Well I too am interested. The Excel-G's I have are significantly different to the originals. The rears are visually quite different but I have not made any measurements to quantify it (see first photo).

The front Excel-G's have a slightly shorter extended length, but I am not sure about stroke. Also the Excel-G's have a 20 mm diameter shaft compared to 22 mm for the originals (also made by KYB). The problem with that is the bump stop which fits over the shaft is now loose, so the dust cover isn't held up high where it can function as a cover. It leaves the shaft exposed.

That is so easy to fix if you remove the strut and the spring from the strut..... Theres a little lip that the boot sits over. Easy to fix but a pain to pull the strut apart for it...... you could get it done if you just took the strut out I reckon though. I thought mine were farked but realised the simple solution.
