TEMPORARILY rough ride - SLS actuators?
 

Hi there,

I recently replaced my leaky hydraulic lines and filled my system with fluid (no idea how long it ran without it - car is new to me). Ride quality or height doesn't seem to have changed much (generally pretty good), but its only sagging a little bit, which isn't concerning me too much.

BUT...

When driving the other day a large man got into the front seat (~300 lbs) and rode for about 10 miles with me. After a minute or two, the ride became incredibly harsh. Then after a few minutes it went totally back to normal, even with him still in the car.

I was afraid I had an accumulator failure, but that wouldn't have gone away like that. I'm confused and worried. Are they about to go? Should I bite the bullet and keep some on hand in that case?

My guess is your valve added pressure to the system until it maxxed out and thats why the ride got hard. Mine does that occasionally when I load it. Not sure what you mean by actuator, but its definitely not your accumulators.
I would rebuild the valve. 300TD on here has kits.

Thanks a lot! That makes sense.

And yeah, I meant accumulators.

I wouldn't worry about it. It takes a while (not usually that long though) for the system to adjust to load changes. For instance, when I have a lot of passengers and we stop and get out, I can hear hissing as the system adjusts to a lower weight by bleeding off some pressure.
