Wiper Arm Adjustment: Front
- Operate wiper, then place switch in OFF position. Lift wiper blade up, then place blade down on glass surface to ensure wiper arm is in full rest position. Check clearance between end of wiper blade and bottom of windshield.
- If clearance is not within specification, adjust wiper arm as necessary. See FRONT WIPER BLADE CLEARANCE table. If wiper arm adjustment is necessary, clean wiper arm pinion shaft threads with a wire brush before reinstalling wiper arm. On I30, tighten wiper arm retaining nut to 15-20 ft. lbs. (20-27 N.m). On all other models, tighten wiper arm retaining nut to 13-17 ft. lbs. (17-23 N.m).
