Hello,

I am looking for some advice on troubleshooting the self leveling suspension on a 1982 300TD. I know that there is a lot of info on the forum about this topic but some of it is conflicting and I would like it from the horses mouth if possible.

I recently changed the fluid and filter. The pump is working. I manually moved the control arm with the turnbuckle type bushing up and down and it seemed to control the level but it will not hold for too long before it rests in the down position (just about a week or two between driving).

Any suggestions out there?

Thanks,

Jared

As a PS to this post, I have found since I took the car out of the garage (winter storage because we have other cars and figure to keep this one rust free) that the SLS is working fine. There seems to be a small leak (drips and hydraulic fluid on the line that leaves the bottom of the res) but other than that it's working well. I'm glad it's working now. Any ideas?
