I hit a pretty mild RR track across the highway in my K5 and it got my right front into some phase where it hopped violently. Slowed down, went away, never happened again.

Had a worn ball joint on a Jeep ZJ that got somr shake at 45 mph. Changed it and fixed.

Was not what Id call DW.

I did get that on a ZJ when steering dampener went.
Bout shake your ass out of the vehicle.

New one fixed it.

Buds kid did a lift on an XJ, 33s and all new suspension. DW scared the hell out of em both.

Told em retighten everything. Said they did. DW remained.
Said tighten everything, claimed they did.

After a few more of me telling him that new stuff shouldnt do that and his kid aint a mechanic, they went back and tightened everything again and the DW was gone.

I ran 4.5 " of lift on two old XJs w 31s. New lower c arms and and it was one finger at 80 on highway, w no sway bars.

Tighten that chit up. Dont use cheap parts ( I liked Rubicon Express back in the day ).
