Hi Guys , recently put my van on a lift and when I lift the van (79 bay) the passenger side rear spring plate seems to stay in the same position that it was on the ground then after a minute or too dongs back down on to its stop Im thinking of putting adjustable spring plates on the rear of it and wondered this is a sign that I'm going to have issues many thanks neil
Sounds like the shock absorber may be sticking - you could try taking it off to see if it makes a difference.
You need to take the shock off and try it again ,bottom bolt will do... I find it hard to believe the shock is the cause, the tortion bars are pretty powerful..
