Air shocks slowly losing pressure.

[ootdega]

Last time I checked them, I filled them to 42 psi. About a month later and they're down to 38, and it certainly feels like it.

I don't think this is normal.

They're Monroe Max-Air shocks that I bought brand new last year. I had the airline replaced as well when they were installed.

So I dunno what the problem could be. Is this normal?

I gave up on air shocks about 1967 for several reasons one was leakage.

I'd put regular shocks on and not bother with all that foolishness.

Not helping.

Slow leakage over that much time is probably to be expected. Tires do it too. Check the connections to make sure they aren't loose but otherwise my best advice would be to check the shocks when you check the tires and top up as needed. I've never had a pair hold perfectly either.

[miamibob]

Actually we ARE helping. Are they still covered by a warrantee? Doesn't sound normal to me either so obviously you appear to have a leak (but then you didn't need us to tell you THAT). If a shop installed them, go back to them. If you installed them, contact Monroe. Sorry we can't see through the computer to find the leak.....

Or has been said, keep them topped off and don't worry about them.

Will do. I was eventually planning on getting a small air compressor to put in the trunk, but it seems I'll have to bump that up the priority list somewhat. There aren't any free air stations around here.

...Oh hey, here's just the thing for 20 bucks. Thanks, Amazon.

Those compressors (generally as I have not checked Amazon) come in REAL handy for quick tire fill ups. Good move to have one at hand. Keep one in all my trunks!!

Another thing about air shocks and handling is if they are not hooked up seperately pushing down on one side like around a corner jacks up the opposite side causing more body roll. Temperature changes also affect pressure and promotes leakage.
Could have loose connections or dammaged in some way also pin holes in the air bag. The more they are pumped up the less shock travel there is when a bump throughs the vehicle upward which can also dammage the system.

Ah. Temperature change, I didn't think of that. That would explain it. Cold air is denser. Duh.

Yes cold air is denser but in this case hot air expands so in a perfect world the car would go up as the temp increased and down when it decreased.

I have found over the years filling tires in the winter come warm weather have to add a few lbs.

[sly]

rubber is porous. it will leak ever so slowly over time, regardless.

Yes, that's true. My point was I didn't notice any leaks during winter, and that was probably because the air was denser at the time. I also had the shocks at 35 in winter and I have to keep them at 42 now to get the same result.

I can't remember the last time I filled them before this summer.
