Bringing Vehicle Into Initial Position For Alignment (1BA)
Due to the different alignment platforms, it may be necessary to raise vehicle at the front axle so that it is possible to insert VAG1925 spacer. After vehicle is lowered, it should be bounced to resettle suspension. To place vehicle in initial position for alignment perform following:
- Install distance caliber (VAG1925) with the adapters (VAG1925/3 or VAG1925/4). See SPECIAL TOOLS .
- Unscrew both thread spindles until they just come to rest against front bolts of carrier. See Fig 1 . This MUST NOT raise vehicle. Vehicle must be standing on its wheels. Vehicle is now in initial position. On vehicles with a level control system, turn ignition on and wait until vehicle height has settled.
- At this point, alignment program checks base toe setting. If toe is - 20'- +40', go to next step. If toe is not as specified, adjust toe-in to specification. See TOE ADJUSTMENT FRONT .
- Place lifting jacks under front end jacking points and lift vehicle 2.4" (60 mm). With vehicle lifted as specified, push cylinder from threaded spindles and fix with safety bolts. See Fig 2 . Ensure that safety bolts are correctly positioned.
- Lower vehicle onto distance caliper. Observe and compare toe-in constant "S" measurement on alignment computer to specifications. See WHEEL ALIGNMENT SPECIFICATIONS . If toe-in constant "S" measurement is as specified, check toe-in. See TOE ADJUSTMENT FRONT . If toe-in constant "S" measurement is not as specified, adjust as necessary. See ADJUSTING TOE-IN CURVE (ALL MODELS) .
NOTE:
When raising vehicle, ensure that wheels do not lose contact with turntables. If wheels lose contact, measurements will be incorrect.
