Soooooo...... this is relevant to my interests. Truck is an 03 RCLB with 2.5" spacers up front, 275 road tires on 18's.
Past few years I've been having some serious, infrequent, death wobble. Year ago I did 2nd design steering upgrade, all new ball joints, poly trac bar bushings, new sway bar end links. Had DW one time pulling an enclosed trailer a few months later, chocked it up to a less than ideal tongue weight .....Then last saturday morning had it again, bad enough to shake off the power steering reservoir cap. Started while crossing some uneven pavement at ~70mph.
Did the 'eyeball' test on the trac bar and steering, no noticeable movement other than some minimal bushing squish.
Been planning on ditching the spacers and going to an OEM length shock (I have new MonoMax shocks, havent installed on front yet), and then see how it drives after realignment. **** sux
