Suspension problem
2000 Lexus LS 400 V8 Two Wheel Drive Automatic 324000 miles

I just bought left and right upper ball joint assemblies and am installing tomorrow. Is there anything I need to know about deinstall / reinstall that is outside the norm?

Do you
have the same problem?

UPPER CONTROL ARM & BALL JOINT
CAUTION:On LS400 models equipped with air suspension, ensure ignition switch is in OFF position before raising vehicle. If ignition is on when vehicle is raised, vehicle automatic height adjustment will operate, resulting in possible damage to vehicle.

Removal (GS300, GS400 & LS400)
Raise and support vehicle. Remove shock absorber assembly from vehicle. See STRUT ASSEMBLY. Remove 2 bolts and upper suspension arm.
On LS400 models with coil suspension, remove front shock absorber assembly. On LS400 models with air suspension, remove front pneumatic cylinder.
On all models, remove bolt, and disconnect ABS wheel speed sensor wiring harness from upper suspension arm. Remove bolts and upper suspension arm.
