So every now and then we get stumped, confused, or completely frustrated with 2/7/9-series. Take heart. It is so much easier than various BS GM products from the same era or later I work on for our racing team.
Examples:
We average one axle per 14 hours...always the driver
We had to upgrade brake on both ends because of repeated CATASTROPHIC failures...keep in mind, even into the early 2000's rear disc brakes were rare on GM sedans INCLUDING higher end items
Changing plugs requires loosening engine mounts and ratcheting strap
Changing a power steering hose requires partially dropping the front sub frame
We run through an average of two wheel bearing/hub assemblies every 24 hours
EVERY vehicle we have bought to run or for parts has had a failed wiper motor "pulse unit" so only high speed works
All of them had failed window switches
3 of 4 had failed driver window motors
All had at least one failed door handle linkages
2 had failed coil pack (multiple packs on each motor)
Rust...holy crap rust...on plastic cars
Plastic coolant fittings that fail catastrophically
Plastic intake manifolds...OK but the gaskets fail and they are used as coolant crossovers so they fill the cylinders with coolant
We had to replace two of four steel brake lines...because rust
All of this one "series" of vehicles that sold hundreds of thousands. Highest mileage vehicle from this group 175K miles.
Granted, these failure happen in endurance racing but...Volvos fair much better.
