Have a 2000 Montero Sport Limited. Bottoms out frequently with only 4 people in car no loads. I'm oringinal owner and problem is getting worse over the years. Replaced all shocks and dealer said the springs were fine............ I might have to disagree with them. Looked on-line for new springs preferably heavy duty, none to be had, not that that would be best for the ride anyway. Any suggestions?

 

there is a bulletin for that.. It basically has someone install a "helper damper" (basically a large pad) that will add a bit of force to the spring when at its most compressed.
