Ok so I have a big problem here,

1999 4Runnert that I just swapped the rear axle and used fj80 front springs, the new one doesn't have sway bar mounts. The front has camburg UCAs, bilstein 5100s and toytec/eibach lift springs. The perches are on the middle setting for the bilsteins. After the rear axle swap and lift with the 80 springs I end up on three wheels even in low speed turns. One person I asked says I don't have enough droop in the front end so when I turn I don't have enough down travel and it's lifting the truck. When the truck is lowered off a jack it only settles a few inches. Another person has told me that without the sway bar it's causing the massive body roll but a lot of guys I know ever drive without a rear bar or didn't notice when it broke off. Driving in a 25mph S pattern feels like I'm in a boat there is so much body roll. Anyone have any ideas on which or both of these is the problem. Thanks

 

Did you lower the panhard bar mount? are you still running the pizza cutter tires?

 

No I was going to order the SS adjustable panhard. Yeah still hAve the skinnies

 

A too short panhard increases roll center?

 

a combo of that and sidewall deflection from the tall skinnies.

 

Even worth having sway bar mounts burned onto the rear axle. Seems like a sway bar is only going to cover up the real problem which is the panhard being too short.

 

You could get a panhard drop bracket. Which tires are lifting? front? rear? are ya sure you're only going 25?

 

Front end is I think. Yeah even slightly swerving within a lane feels VERY tipsy. Going by what people say about the roll center a drop bracket makes more sense but Steve Schafer says they don't work.....

 

what's wrong with returning the geometry back to stock? Get an adjustable pan hard then. Try to get some video of it happening. Ive burned in two drop brackets for two third gen buddies and both told me it improved sway and wander.
