Our ’97 TJ is a pretty budget-minded wheeler and still uses stock control arms and suspension geometry. Now having said that, the Jeep is not stock, and does have lockers, 35s, and a swapped-in Toyota rear axle. Plus we wheel it hard. We also run a slip-yoke eliminator on the TJ and that necessitated an upgrade to adjustable lower control arms so we could rotate the rear pinion up a touch. Still all four front control arms are stock as are the upper rear control arms. They work, but are weak compared to aftermarket components. Ours were showing wear, with the bushings looking sad. The stamped steel was scratched, bent, and even stretched out in a few spots. Time to upgrade.
