Vehicle Wobbles.

Hello, First I'd like to thank you for all the help! I have been on this forum for a little while now. Even though this is my first post, you have all helped me a lot with Hiace issues!
My problem. I have a wobble at speed as if the wheels move independently from the body of the Hiace. not fun.
Iv replaced rack ends, wheels bearings, welded sway bars, and had an alignment. All helped (stopped it from tramlining) but have not solved the original problem. Feels as if a heavy wind is pushing me all over the road but the trees are calm. Turning corners is sketchy as it feels like the wheels tilt under me. And ALL little tiny bumps in the road now push me around. It was super solid on the road up until a month or two ago.
Please help! I love this van and have taken it all over town to assess the problem but no one can tell me. I thought I had traced it down to control arm bushings but the mechanic said it can't be the issue I DON'T KNOW WHAT TO DO. The problem is getting worse and this van is my life.
Thanks for any help.

late response .. however ..
Is it speed determined ? or its a constant regardless of how fast or slow you are going?
Does your steering wheel move/constantly shaking while this happens?

Possible things to check out..
wheels: are they buckled?... Have wheel weights come off.. Are the wheels balanced?

try swapping the fronts to rear .. see if that helps.

Hoping you've sorted it by now.

Hey man, Ill have a look at balancing. Its alot better now after doing all these things and some but still! When turning corners at speed the steering wheel shakes and feels like the wheels are moving stil, not sure if wobble or in-out...

"Not fun" I know. I have same problem when wind gets up. Otherwise town centre driving is fine and if not windy motorways are ok at up to 60mph. But van doesn't feel 100% secure at higher speeds. Be interested to know if you manage to fix this.
