 Raise and support the vehicle chassis with jack
stands positioned behind the front lower suspen-
sion arm brackets.
 Raise the axle housing back into position and sup-
port with a hydraulic jack. HINT: The axle housing

axle drooped, as this will place tension on suspen-
sion arm mounting hardware.
