OUTttNE
OUTLiNE OF CONSTRUCTION
l TKe construction and operation of the front and rear axles are basically the same as previous models.
l Because of the use of a high power engine, the following parts are modified to improve rigidity.
(I) Larger front and rear bearings are used.
(2) Larger front and rear knuckles are used.
(3) A five-stud wheel hub is used.
l An ice scraper is newly installed on the rear knuckle to prevent ice from building up on the brake caliper.
