Overnight, my car went from a soft ride to feeling like riding on bricks

First of all, it is not due to a change in outdoor temperatures.

It happened after I had started off and driven about 1/2 block before I felt that the right front tire had gone flat. When I got the tire fixed, I had the mechanic check both the rim and the tire for any damage that might have occurred when I rode on it. There was none. I had the tires rotated and balanced and now the repaired tire was on the rear.

But, from that point onwards, it felt like my AGX's had been set to 4/8 instead of 1/1. I checked them and they were still on the minimums. The tire pressure was the same (32/32). So, what gives?

The car rides straight and does not veer as if the front end were out of alignment.

Any thoughts?

AGX's ride hard, even on 1 they are very firm.
What did you drive while you had your tire fixed? Getting back into your own car after driving something else really allows you to feel your ride.

Are you sre that it's not temp related? I can feel the difference in my ride with a temp difference of 10 degrees C. AGX's do ride hard and they are very dependant on the temp.

Yeah AGX's are very touchy with regards to temperature. Thats about the only thing that would make sense, unless you some how damaged both struts?

I thought the higher number on the AGX's meant a softer ride?

Is it possible that before, your PSI was really low?

on the struts for the agx's, 1 out of 4 is soft and 4/4 is firm. Same for the rear shocks, but its out of 8.

We had several temperature swings for the past two weeks, and I have observed that they ride harsher when the temperature goes below 60 and softer when the temperature is above 75 -- which it was the same day I found the flat and and had it fixed.

I tried turning the dials to higher settings to see if they rode even harsher, and they did.

The rear shocks have a solid feeling dial for setting, while the front dial (if you could call it that) is very flimsy --so much so that the decal on top has almost worn off. I can still discern the small patches of colors for each setting, though.

One thing I never bothered to find out is if it matters in which direction they are turned...like going clockwise raises the levels, but the dials can also move in counterclockwise.

Just wondering if you have to turn the dials in the rear a full rotation in a clockwise direction to go from 1 thru 8, or if you could simply turn it counterclockwise one notch to go from 1 to 8. I've done both.

This raises the question of "How can you really know for sure that if the dial says, "1", that it matches the corresponding setting inside the strut/shock?

I'm going to have my suspension checked out to see if any bushings have gone bad since I replaced them last year. I know that I need a motor mount, but the rough ride happens when coasting, too.

i think it could be something going on with tire pressure.

I check it frequently and it has stayed the same on all fours.

I've also experimented with different pressures and found that 32-33 is the ideal setting.

So, I don't see how tire pressure can be the culprit.
