💡 What replaces worn sun gear thrust bearings to fix harsh shifting?

Upgraded copper alloy washers cut sliding friction while soaking up shock loads from heavy towing. These rebuilt units are a handy upgrade for tired drive trains struggling with delayed forward motion. Here is why shops prefer this route over partial shim patches:

- Exact dimensional clearance eliminates lateral shaft wander during rev matching - Plasma coated face plating shrugs off heat buildup in traffic crawl conditions - Laser scored fluid channels draw fresh gear lube toward the highest stress zones ✝️
