Thread: Air Suspension and Compressor - technical help needed

Replacing the piston and cylinder will go a long way to making them last for sure.

I am at only 142,000km original everything with the air suspension
I was just going to buy new everything if I decide to play crank roulette, how long should I expect the compressor last and what’s the cost difference between replacement and rebuild ?

You will have an AMK compressor so you can only service the drier as parts aren't available unlike the Hitachi, rebuild about $250 to replace everything available versus $700 plus for a genuine Hitachi.

I would look at a service kit now before you start having any issues.

For the sake of 450 difference I would just buy anew unit
i Will look at getting the dryer beads replaced and get a whole new unit ina few years if I still own it
I am thinking a couple more big trips before replacing the whole lot if I keep it

even with replacing the bags and compressor with new it’s still cheaper than aftermarket suspension every 8-10 years from brand new
i never have a never understood how some rave about how good their 4wd is when they throw away brand new suspension to replace it at a cost of 1000’s to get a decent set up them claim LR air suspension to be expensive and unreliable

Those estimates are for a Hitachi, double that for the amk but the service kit is cheaper as there are less replaceable parts.
So more like 4 x the service cost to replace.

Bloody hell....

I got 12 years out of the first AMK, so just threw in a new one...

I swapped my Hitachi out for an AMK, as at the time, the Hitachi's were considered inferior to the AMK unit.

Annoyingly, I had the mechanic do it, so I didn't keep the old part for repairs. That said, I will probably simply follow Tombie's lead, and replace the whole damn thing when it goes.

Buying yourself ex UK it is around $1000 delivered Hitachi or AMK but the service guys seem to turn it into a $2k+ job buying at local stealer prices plus labour so the $200 to rebuild the Hitachi properly every 8 - 10 years is worth it.

There is no rebuild option on the AMK other than desiccant which I tried on my mates 2015 D4 to no avail then swapped to a new one. That was last year so they got 8 years. It was faulting for a good 6 months prior to me getting involved.
