- Clean grit off wheels and floor. Debris in the bearing shortens service life and skews readings.
- Keep locking pins installed until the vehicle is stopped, parking brake set, and rear wheels chocked.

About the plates.
AutoSolo Turn Plates let you measure turning angles during a home wheel alignment. They sit under the front tires and rotate freely, so the wheels can pivot naturally while you read caster, check toe-out-on-turns, or run the 20° sweep.
Pit-rack turn plates
For use on a pit rack or alignment rack. The vehicle is already raised, so plates sit directly under the front wheels without ramps.
Drive-on turn plates
For driving the vehicle on at ground level. Pair with ASRP004 Drive-On Ramp Kit for leveled entry.
Which do I have?
Check the SKU on the packaging or the sticker on the underside of each plate. The ASRP004 ramp kit pairs with the ASWG004 only. ASWG008 plates ride on a raised rack and do not need ramps. Replacement transition bridges are model-specific, ASWG008-TSB for the ASWG008 and ASWG004-TSB for the ASWG004.

03 · Safety
Before you begin.
!Read before use
- Work on a flat, level, hard surface. Concrete or paved floor. Uneven ground is unsafe and skews readings.
- Do not exceed 4,000 lb per plate or 8,000 lb per pair.
- Never roll the vehicle onto the plates with pins removed. Keep locking pins installed until ready to take measurements.
- Always chock the rear wheels before starting alignment work.
- Never work underneath the vehicle without jack stands.
- Keep bystanders clear during drive-on and drive-off.
Work area
- Keep the work area clean and dry to avoid accidents.
- Children should not handle or be near this product during use.
- Store idle equipment in a dry location. Keep out of reach of children.
Personal protection
- Wear ANSI-approved safety glasses.
- Use non-skid footwear.
- Avoid loose clothing or jewelry that can catch in moving parts. Roll up long sleeves. Tie back long hair.
Condition
- Maintain proper footing and balance. Stay alert throughout the procedure.
- Inspect pins, scale plates, and bearings before each use. Replace damaged parts before continuing.

!Leveling the vehicle
- The ASWG004 raises the front wheels. The rear wheels must sit at the same height, or the readings are off.
- Recommended: ASRP004 Drive-On Ramp Kit. Matches plate height with a smooth, level drive-on path.
- Budget alternative: Place a flat plank 1 in (2.5 cm) thick under each rear tire.

06 · Measurement
Using the plates.
Turn plates don't, by themselves, tell you whether alignment is in spec. They enable the measurements your gauge needs.
Caster · 20° sweep
Turn the wheel 20° OUT, zero your camber gauge, then turn the wheel 40° total to 20° IN and read. Verify against the turn plate degree scale. Your gauge's instructions (or the vehicle service manual) convert the reading to caster.
Toe-out-on-turns
Turn the steering until the inside wheel reads 20° on its plate, then read the outside wheel's plate. Compare to OEM spec. A mismatch indicates a bent steering arm.
Typical OEM tolerances
| Measurement | Typical OEM range |
|---|---|
| Toe | ±0.10° to ±0.25° per wheel |
| Camber | ±0.5° from spec |
| Caster | ±0.5° from spec · L/R diff <0.5° |
Always consult the vehicle's factory service manual for its tolerances. If readings fall outside the OEM range, a qualified alignment shop is the safe choice.
07 · Drive-off
Exiting the plates.
Center the steering wheel
Reinstall both locking pins in each plate

Release the parking brake
Quick reference checklist
| Step | Action |
|---|---|
| 1 | Prepare flat, level, clean surface |
| 2 | Position plates under front tires · pins installed |
| 3 | Drive on (ASRP004 ramps if needed) · stop centered |
| 4 | Parking brake on · rear wheels chocked · engine off |
| 5 | Remove pins · plates free to rotate |
| 6 | Take measurements with your alignment gauge |
| 7 | Reinstall pins before driving off! |
!Never
- Never drive on or off with pins removed.
- Never exceed 8,000 lb per pair.
- Never work under the vehicle without jack stands.
08 · Care
Care & compatibility.
Cleaning · Inspection · Lubrication
- Cleaning. Wipe with a damp cloth and mild detergent after each use. Avoid abrasive cleaners and solvents that attack rubber seals.
- Inspection. Before each use, check pins, scale markings, and bearing rotation. Plate should rotate smoothly with light hand pressure. If it binds or grinds, stop using it.
- Lubrication. Apply a light coat of white lithium grease to the bearing periodically. Do not over-grease. Excess traps dirt.
Troubleshooting
Plate binds or grinds
Clean grit from the bearing. Apply light lithium grease. If binding continues, contact support.
Readings differ wildly L/R
Confirm floor is level in both directions. Recheck tire pressures. Unequal pressure skews results.
Wheel rolls off plate
Re-center the vehicle with a spotter. Confirm rear wheel chocks are firmly seated.
Scale hard to read (ASWG004)
Wipe scale clean. Read from standing height. Low angles make markings hard to align.
