Yeah it’s hard if not impossible to find any American made hubs for our TBs these days

According to NGK the 90220 LTR5AHX Ruthenium are pregapped to .043" so those should require no adjustment? This is interesting:

Hmm those may be worth a try, $8 on RockAuto FitsTrailblazer Base Model; Gap 0.050" orTrailblazer EXT; Gap 0.044" Is that correct?

Okay I have a Bluetooth OBD will torque pro be sufficient?

Okay I will check them, if I do decide to replace the spark plugs should I also replace the coil boots/springs? A kit of 6 new isn't expensive at all from RockAuto.

I've had good luck with SKF hubs

Okay well you stated it could be the amp which is in the trunk and separate from the head unit. If that is bad it’s going to need to be replaced or a new head unit won’t solve your issues. What is your budget? That will really depend on the recommendations you will receive. This can get pricey...

So you want to retain the Bose factory amplifier speakers?
