Inconvenience

To tell the truth, a critical problem was found while brake shoe adjustment, considerable backlash on right rear hub bearing. The rate of clearance has enough capability to cause strange steering actions.
In very near future,replacement of rear hub bearings on both sides would be performed, involving the replacement of trailing arm hinge bushes inner and outer on both sides.
Complicated and troublesome procedure of removing torsion spring separation step must be experienced no matter how I may agree or not.
I must do that if this VW 1302 Super Beetle may be continued.

According to my experience for these 10 years on wheel alignment adjustment principle,15 seconds(angle value) error of thrust angle is enough to produce the strange steering action while straight running.
So the rate of backlash found yesterday was big value enough to destroy the reliability on measuring alignments basic point,it would be no meaning to measure and adjust wheel alignment now with wheel hub backlash on rear right side.
Wheel alignment should be established under the solid and fixed mechanical wheel constructions, the backlash must be as less as possible.
My Beetle would be corrected on wheel alignment and axle construction geometry when the replacements of rear hub bearing on both side were performed and elimination of backlash were established.

As replacement parts on hub bearing, I dare select Japanese production because of the reliability in quality control of domestic industrial companies, NSK,NMB,NTN and NACHI.
Before all,I must know the size of the bearing to be replaced into Japanese ones,based on JIS(Japanese Industrial Standard) or ISO(International Organization for Standardization), probably the former considering ancient production periods.
