Air Spring reseal kit (LR016412)

And another perspective for driver's side wheel well after rebuild and re-installation.

I recently changed out all 4 air struts with equipment from BA, OEM by Delphi. An independent shop said springs need changing, no leaks, but at 90k miles, I decided to change the whole assembly as I plan to keep using the rig for many more miles and wanted peace of mind.

The driving feel improved a lot, but there's still a wallowy feel that I was expecting to go away or improve a lot. It didn't. In fact, sometimes a I feel wallowy feel increased going around corners. Will LCA help? I think front lower LCAs are going (beginning to feel the slight bumps at full stops or going through bumps on road).

Is there a hardness calibration or did I just use wrong struts (I hear arnott's are less wallowy)?

The newly painted and refurbed struts on newly painted mounts.

A local mechanic quoted me $7k to change all 4 air struts. Swear to god. He had $550 labor for each corner and Land Rover brand air struts all around. I'm so glad I didn't need to service them lol. I'm super easy on it off road. I drive it slow if its bumpy and the air suspension works its best that way. Its more comfortable too. A lot of guys like to drive fast and the LR4 can do it, but it costs money to drive fast off-road.

As an aside, in the first set of pics, the fender showed mud in the lower part. As you may know, if that isn't removed you'll likely have a rust hole there in the distant future.

There is no hardness calibration or setting like with oil struts. That said, what about the rest of the suspension? There are a lot of other components like links, sway bars, and bushings.

Thanks @powershift -

Yes, (all) the mud is slowly getting removed and things getting cleaned/repainted (give us time!) I was frankly surprised how much stuff has accumulated everywhere in this thing...there are a lot of nooks and crannies which you only see when everything gets torn out. So rust prevention is coming!

That sound like a lot of money to do the struts.... A lot of folks are replacing these by themselves at this point (and you don't even need spring compressors!) You can do that job in a garage with just floor jacks and stands and it makes sense to work on those when you have to do the control arms / bushings - which is what I am doing. And those struts seem pretty tough and reliable so rather than replace, which isn't cheap, I opted to service. Thus the source of my question - are there any issues with serviced struts?

Also - you are 100% right: speed kills. I have wrecked a rear strut driving too fast at night in Africa (into a massive pothole). I bent the strut (fortunately not the frame) and cracked a factory wheel (alloy rim). I didn't know about the strut at the time but suspected something was wrong (the truck wasn't leveling correctly). I ended up back in the states and when I was getting the truck serviced (before the fuel sending unit / tank low pressure pump failed) the mechanics were scratching their heads about the back end...apparently no one there ever saw a bent strut before and couldn't figure out how I did it (just plain stupidity). Fortunately, it was replaced under warranty but to your point: slow and steady wins the race (and saves big money on totally unnecessary repairs).
