FRONT DRIVE AXLES CHAPTER 5 Classroom & Lab Page 99 YOU
SHOULD BE ABLE TO Explain the purposes of a FWD cars axles.
Describe methods to offset torque steer. Name and describe types of
CV-joints. Name and describe designs of CV-joints. Explain how a
ball type CV-joint functions. Explain how a tripod-type CV-joint
functions. Page 99 DRIVE AXLE CONSTRUCTION
Two drive shafts, made of three pieces. Axles pivot on CV-joints,
inner and outer. Outer CV-joint is supported by the steering
knuckle. Inner CV-joint connects to the differential. Page 99 DRIVE
AXLES Equal Length Shafts Page 102 Vibration Dampers 102
Unequal Length Half-Shafts104 Drive Axle Supports104 CV-JOINTS With
out CV-joints FWD would not be possible.
CV-joints transfer torque at a constant rate. CV-joints can operate
through a wide range of angles. U-joints DO NOT provide a constant
speed. Page 104 CV BOOTS Boots keep lubrication in.
Boots keep dirt and moisture out of the joint. DO NOT INSTALL SPLIT
BOOTS! Axle must be removed to install new boot. CV-joint must be
completely disassembled, cleaned, and inspected before replacing
boot. Always use new clamps. Page 105 TYPES OF CV-JOINTS Inboard
joints are of the plunge design.
Outboard joints are fixed. Page 107 CV-JOINT DESIGNS Two basic
designs; Ball Type Tripod Type
Both are available in fixed or plunging. OUTER CV-JOINT Two basic
Types; ALL OUTER JOINTS ARE FIXED.

Page 107 INNER CV-JOINT Three basic Types; ALL INBOARD JOINTS ARE
PLUNGING.

Joints are replaced 9 to 1 more than inner joints.
Wear causes NOISE, or VIBRATION. Replace punctured boots
immediately. Disassemble and clean joint completely. Use all of the
grease supplied in kit. Use new clamps. Page 113 REPPEZA FIXED
