I have a 99 XJ with front end bounce not DW, the steering wheel feels like the tires are bouncing like a basketball. It steers during this and will go straight unlike DW. We have a 4” lift with aftermarket trac bar and pitman to match the lift. I’m running 265-75-17 with spider adaptors from 5x4.5 to 5x5 for “09” Wrangler Rubicon wheels. The caster has been move both positive and negative with no help (now at 6). The control arms are also aftermarket (Rusty’s for all the front end parts changed). We have braced the front core support and redone the welds. The tie rods are braced with angle iron to stiffen them. The springs are about a year old for a V8 Grand Cherokee with 2” spacers, shocks are Rancho 9000 and they are on adaptors for loops both ends.
Last change was a gearbox that showed a little play no help. The shop helping is good and builds sprinters. They work on lifted trucks all the time but this XJ has beat us. This just started about two months ago after I put my summer tires on with less aggressive treads, same tires I ran last summer with no problem. The dance starts with the 60+ hit a bump just like the DW and we have to brake down to about 15-20 mph for it to stop.
I know the feel of the DW and everyone who has not driven the XJ says that’s what it is, but after driving the XJ (watching their eyes get big was great) the tune changes. Side note running 8.8 in the rear. Trans is dropped to match angles. We are open to any and all help.
