Inspection After Disassembly

Clean the disassembled parts. Then inspect the parts for wear or damage. If wear or damage are found, follow the measures below.

Drive Pinion and Drive Gear 

• If the drive pinion and drive gear teeth do not mesh or line-up correctly, determine the cause and adjust, repair, or replace as necessary.
• If the drive pinion or drive gear are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new drive pinion and drive gear.
• Drive pinion and drive gear are supplied in matched sets only. Matching numbers on both drive pinion and drive gear are etched for verification. If a new drive pinion and drive gear set are being used, verify the numbers of each drive pinion and drive gear before proceeding with assembly.

• Bearing must be replaced with a new one whenever disassembled.

Side Gear and Pinion Mate Gear 

• If any cracks or damage are found on the surface of the teeth, replace with new one.
• If any worn or chipped marks are found on the side of the side gear and pinion mate gear which contact the thrust washer, replace with new one.
• Replace both side gear and pinion mate gear as a set when replacing side gear or pinion mate gear.

Side Gear Thrust Washer and Pinion Mate Thrust Washer 

• If any chips (by friction), damage, or unusual wear are found, replace with new one.

Gear Carrier 

• If any wear or cracks are found on the contact sides of gear carrier, replace with new one.
