Humming
Rattle or chattering
Right cylinder end soal squeak
Pump noise. though not loud,lrom the vslvo bodv unit can be heard when turn-ing the steering wheel right or left. This is normsl.
Humming due to pulsation ol fluid is no.mal, paniculady when wheel is turnedwith ca. stopped.
lf equipped with automatic trans-mission, the hum could b€ tor-que convener or pump notse.
Confirm by temporarily removingpump b€lt.
High pressure line touching theframe,Reposhion tho line.

Column shaft wobbling.Replace column assembly.
Check the rack guide for properadjustment (16o page 17-21).Adjust, if n€ca€ssry.
Rattling sound and feeling when turning the steoring wheel right and lett with thoengine OFF is a sound when th6 valve unit contacts tho stopper. This is normal.
Striking sound wh6n turning the ste€ring whoglfully right o. left is a sound whenthe r6ck end contacts th6 stopper. This is normal.
