I have a 2002 Envoy, although you Trailblazer owners may run into the
same thing My dealer does a 30,000 mile service for almost $400 that
includes numerous things: new air/fuel filters, numerous inspections
of various systems such as cooling, brakes, etc. Couple items on the
list caught my eye and made we wonder:
1) "drop" the drive shaft, inspect, and lubricate
2) fuel injector service; detach fuel filter and run cleaner thru
injectors, decarbon throttle body, etc
I use good top-tier gasoline, and occasionall Techron, so I'm
questioning the need for a fuel injector service at this time.
Secondly, does that sound right about "dropping the driveshaft" and
lubing/inspecting it? Have any of you Envoy or Trailblazer owners had
that done on a routine 30,000 mi, service? I hate to have things
"dropped" and reassembled if not needed.
Thanks for info.
