Bump

Anyone?

I will probably just have to take the springs out and have a look in more detail. Was short on time yesterday

Hey mate, I rang polyair recently for advice on installation as I'm looking at getting a set soon. They told me the way they run the airlines out is to remove the big upper bumpstop and you will see a hole to run them up through. They also said it's very important to get some exhaust heatshielding going as the exhaust sits too close to one of the bags

Hi TC.Barky, thanks for your reply. Couldn't see the hole you mentioned, maybe I need to remove the bolt that held the bump stop in place first. Will have a look in the next few days.
The kit I bought included heat shields. Im quite impressed with it. Only cost $130 delivered from the US. If you want the link to have a look let me know

Cheers

Finally got round to installing the airbags. Decided to insert them upside down having removed the bumpstop bolt. So the airline comes out from the bottom and not the top as the instructions suggested. Had to remove the coil springs in the end and drill a hole in the center of the base plate that the spring sits on for the hose to fit through. Will invest in some rubber grommets to prevent the hose chaffing on the metal.
With the minimum 5psi in the bags I am left with around a 2cm rear lift!

I ran the hoses over the petrol tank to the back and fitted the valves in the rear bumper. The car handles better on road. Less role when cornering and less vibration in the rear. Not tested off road yet...

Interesting you chose to run them that way. I did mine a week or so ago and just ran them through the hole in the top of the coil seat that is there after you take the big internal bump stop out. Reckon there is any risk of the line getting snagged underneath?

Is that the diff breather I see without a hose on it?

**mat02920** · 27-12-13, 06:28 PM

I really wanted to do it the way you did however mine didn't have any holes to run the hoses where you described. Well there was one but it was way off center so the hose would have been bent/pinched by the airbag. With the large bumpstop retaining bolt removed the there was a hole left but it was closed at the top.

I think my hoses will be ok, Ive neatened them up a lot more than shown in the photo with cables ties. Time will tell I suppose... Another Fraser trip coming up mid January

so this will be a good test

I thought that too but it seemed to be blocked off. There is another on the front of the diff with a hose that goes up to one of the crossbeams.

What ya recon?? May consult the manual...

If there is a hose that runs up to the round tube you should be ok, there is a plate at the top of your springs that is held in by 3 bolts and the bump stop bolts to that.

Yeah this. I took it all out as one unit by taking the bolts off at the top rather than unscrewing the internal bolt of the stop. Plate and stop just fall down and the hole is conveniently left. Should be fine as youve done it though as long as nothing is putting pressure on the bag and the line can't get snagged.

Ah. I get you now! I left the plate/3 bolts in place. Oh well, they're in and all appears to be working well so far. I may look into refitting them properly in the future. Those three bolts were just a pain to get to so I left them.

Thanks for your help guys

**my.paj** · 27-12-13, 07:14 PM

The problem may be that the plate at the top is to small for the bag to sit on.

I just went to have a look. The upper plate is depressing the airbag more than I thought it would so I will have to remove them.

Is there a particular tool you used to remove the X3 bolts holding the plate on? The plate makes them quite difficult to get to and my spanner wont fit nor can I get much leverage...

Any advice much appreciated

Ratchet spanner is your friend (wish I had some :-P). The ones with the curved shape are fiddly. Couple of mine were VERY tight. Think it was 14mm but could be wrong
