Alright folks, I am here to report on further findings.
The front sway bar has multiple cracks but has not actually come apart like some I have seen online. The cracks don't go all the way around. Am I right to think I need to replace it soon-ish, but it is not the cause of my problems?
The rear leaf springs are flat. This is something I saw a couple days ago, but did not process until lying in bed last night. 'Wait a minute... aren't they supposed to arc?' Yeah, they are.
The leaf springs are generally agreed (in van forums) to be too wimpy even when new. There are heavy duty and add-a-aleaf options, but they have various drawbacks (add too much lift, don't fit existing brackets, etc.). I will look into smkettner's alternative thingy more.
Questions:
- Are the leaf springs the reason the van sways in the wind (parked) and corners terribly (driving)? Or do I need a rear sway bar ALSO?
- Is the front sway bar ok until I get home (100 miles, 2 months)?
Thank you all so much!
