Procedures 

 

Get Vehicle Information 

Ask  the  owner  for  vehicle  drivability  problems, 
symptoms,  and  wheel  alignment  history,  and  find 
out  vehicle  information  such  as  make,  model  and 
year, etc.   

 

 

Check each chassis part carefully, including rubber 
boot, bearing, rock arm, tripod end, shock absorber, 
tie  rod  end  and  steering  mechanism,  for  any 
looseness  or  wear.  Then  check  to  see  if  the  tire 
pressure, tire treads of the left and right wheels are 
alike. 

Wheel Alignment Checking 

Perform  the  wheel  alignment  checking  after  the 
initial condition is known. 

Adjustment 

If the measured values are not in accordance with 
the specifications given in the databank, the wheel 
alignment adjustment should be performed. 

Test-drive 

After finishing the wheel alignment, test the vehicle 
to  see  if  the  abnormal  conditions  are  eliminated. 
Re-perform the wheel alignment if necessary.
