4 bolts, Dead simple, sort of.

Stuff needed:

2 Axel Stands
2 Bricks
13mm socket
15mm socket
Trolley jack
Breakers bar is really handy
HAMMER
4 bolts, 10-15mm longer than the current 4 on the ARB.

Put bricks in front of the front wheels to stop it rolling (life saver, good job i did this :) )

Loosen off rear wheel nuts

Jack rear of car up onto axle stands

spray the four bolts with WD40

Take rear wheels off

Undo the four bolts that go through the ARB 15mm for the fronts and 13mm for the backs

Now comes the tricky bit, Take the ARB off (probably fell off when you undid the bolts) get both arbs and lay them on top of each other, you need to offset them, for instance the top arb, the mounting bracket on the right touches the rear beam, but on the left hand side the bottom arb bracket is the one against the beam. This will make more sense when you try it out as there is no other way of doing it :)

Put a shock bolt through one end of the ARBs, this will hold them in the right place while you try and line the other end up with the bottom of the shock on the other side.

The first side will go in pretty easily, put a bolt in it to hold it in place, may need a few good taps with the hammer to get it well in there.

Now you have to line up the other side, this is just a bit of good old fashioned brute force, and a hammer. just keep pushing / pulling and hitting the end untill you can get it on the hole for the rear shock, then whack a bolt in it, dont do the bolts up yet.

The two smaller bolts, at this point i put the jack underneath the arbs to push them up to be level with the holes, make sure none of the mounting brackets get caught on the axle on the way up as they will bend. Once theyre lined up, put a bolt in and repeat for the other side.

Next Do the shock bolts up tight, youll have to alternate sides otherwise youll get one done up tightly and the other one wont reach the threads :)

Finally do up the 2 smaller bolts.

Congratulations :)

Glad to see someone doing this! :chill:

You could have cleaned it up a bit though and Fitted Polybushes! :insanity:

But a Good Guide *Thumbs Up*

Mine has really stiffened up which in theory has reduced the understeer, my next cornering upgrade would be an LSD tho as mine always spins the inside wheel when im pushing it :rolleyes:

where do you get longer bolts would the standard ones not do fine?

To update this makes the back end stiffer, Original bolts are too short to go through both ARB brackets. Finally this mod didnt work so well because I found that it snapped the mounting brackets.
