P38A Best AirBags - About to ditch the Coils

Yes you can follow them back until they get to above the back axle then you cant reach them. I would push new ones thru. There is a chance that a blown exhaust may have melted them causing the PO the change to coils. The originals are clipped in place and are a bitch to remove
 
Airline for N/S bag goes down O/S of car and across body rail above and to rear of tank then forwards to N/S bag. Airline for O/S bag goes down N/S of car and in clipped to other pipe across body rail then forwards to O/S bag.
 
I was thinking if he cannot see the end then maybe it has been cut off or tied aside somewhere. If he follows it back he might get lucky and find it tied aside somewhere. Failing that, any decent supplier like Airtek (or was it Activ Air?) will have loads of 6mm airline lying around dirt cheap.
 
HAd that issue with not fitting one side properly either.

File the top plastic down gradually until it fits, ensuring the groves are the same! 20 mins to file down properly. Just do a little at a time and try and refit.
 
Found the airlines had to trace them back but at least they weren't cut, just folded back.

Thanks Falk I had to file the rear bags to get them to fit. Pretty surprising considering they are oem Dunlop ones!

Now to do the fronts which should be a lot easier just need the rain to stop....

Possibly more to do with the shit encrusted aperture than the air bag cap.
 
Only just managed to get one front Spring out today, had to go buy some Spring compressors as my shortcut method that worked on the back didn't on the front!

Still I'm gonna take a day off and finish the job tomorrow, even if it requires a not so glamorous assistant holding an umbrella :/

Have read approximate psi levels for each bag for standard ride height is F65 R55, sound about right?

I know it's not going to be an exact science without the eas system doing its thing.
 
They are made to OEM spec, but i compared them to my LR genuine when on removal, only discrepancy i found was the intake valve - the height difference meant i couldn't fit the clip - as you found out :)

The OE bag is bigger where the air intake is, in terms of depth, compared to and dunlop equiv. I put it down to LR esteemed quality control on the fittings :)

That's funny because i changed mine a couple of years ago and the Dunlop OEM ones were exactly the same as the original bags i removed, i cleaned out and treated the cap seating and they fitted straight in. Snugly but no filing needed. Land rover don't make the bags Dunlop do.
 
I cleaned out the cap seating although it was clean to begin with and there was nothing to make the bag stand off the surface, took about 5-6 goes at filing then trial fitting before they sat high enough to only just get the pin through.
 
Well, got the bags fitted fronts were easy but the springs were a right b@"?! to get off!

Anyway had loads of fun trying to inflate the bags evenly using the schrader valves!! Talk about chasing your tail.
Read I should have 65psi in each bag up front and 55 on each rear bag for a close to standard ride height.
I got it as level as I could with only one rear corner 10mm less than the other 3, but I couldn't get the rears to go up anywhere near high enough at 55psi. Have 55 in the front now and 65 in the back.

On the test drive, well on a smooth A-road the difference is amazing, lovely and firm and smooth.....however on a bumpy B road it's way worse than it was on coils. Even bottoming out at the back in some roads it never did before.

So I'm hoping this is due to having more air in the rears, looking forward to the cable/ect arriving from Datatek and firing up the eas system. Hopefully not to discover that I need 4 new height sensors but I've come too far to go back now!

With 65 PSI in the rears it won't be bottoming out unless the boot is full of bags of cement. You should have for standard ride height, 470 mm from centre of wheel to lip of arch. Any more than that and arse end will bounce around over bumps at speed.
