Question about 1992 Mitsubishi Galant
92 Galant, 80k miles, 5-speed manual transmission, "suspension warning light" is on, but car seems to drive just fine. owner's manual suggest adjusting towed load, or if parked on hill reset to "Auto", etc., none of which are relevant. What is wrong, how do I reset it?
From the expensive lesson that I had to learn about my 92 Galant I would imagine that with the mileage on the car, if the suspension has not been serviced, you might have tiny cracks and pinhole leaks on the inside fold of the airbag from dryrot or wet rot. These cracks are hidden and very hard to diagnose with the "soapy water test" unless the air bag is fully inflated. Once these cracks start, the air bags become very hard to keep inflated which may overwork your compressor. (compare it to yourself trying to blow up a balloon with holes on it.. you may try for a while, but eventually you will give out) The air ride systems are PLAGUED with problems and expensive to repair between dryers, compressors, air bags, solenoids. ALSO, I learned that air bags are not designed to withstand temperatures below 40 degrees or above 94 degrees.. outside of those temperatures, their vulnerability to weakenbecomes MUCH greater.
When I bought my Galant, I didn't realize that the previous owner had probably noticed some suspension issues coming down the pipe line at him and sold it off quickly at an AMAZING price. Turns out that around 60-80K miles is the average life span for many air bags and compressors in the suspensions out there. (I didn't know this when I bought the car) I had to have the compressor replaced at the recommendation of my mechanic, only to have the new one go out again shortly after because they didn't know that it was actually the air bags that were killing the compressor. I didn't have enough money after JUST buying the car to keep taking it to the shop. A friend of mine converted his Ford to a passive coil spring system with Strutmasters.com - He doesn't drive a Galant. He drives an Expedition, so I suspected that they probably would not have the kit for my 1992 Galant. I was surprised to find that they did have a kit for the car
I was also surprised to find out that I could convert ALL FOUR wheels for less than $600 (which coincidentally is about how much I spent on the repairs that didn't help before I considered the conversion kits) Anyways, that is my ten cents for what it is worth. I am very happy with the conversion kit. Even though I have had other problems with the car since then, the suspension has not been one of them. I hope this helps!!
