Keep in mind the autotrac transfercase has a viscous clutch system allowing it to slip inside the transfercase. Ours is direct. No give at all. 97-older Bravadas had the viscous clutch transfer cases, made by Borg Warner. Model 4472, IIRC. Basically the same t-case that was used in the Cyclone/Typh...

crew cab sonoma

The Bravadas use the same CV axles as the 4wd's do, and they don't seem to have any higher CV failure rate. If the transfer case is disengaged, there's really no significant difference in work load on the CV's wether the front front axle is engaged or not, as long as its a stock open front different...

Just FYI, all 2003-up 4.3's come factory equipped with the "upgrade"
poppetless injectors.
For 2003, the LU3 engine replaced the L35. The key change for the LU3
was the new style injectors.

thanks for the info HenryJ.
i knew it was larger than my Ext. Cab,
i just didnt think it was that much bigger.
some GM's do have hollow swaybars.
some C4 Corvettes definetly had them.
in fact, i traded for a set for my 86 Vette.
they weigh about a third of what the
original Z51 bars weigh.

just wondering what the diameter of the front stabilizer bar is on the Crews. i never measured the one on my crew while i had it, but was sure it was larger than the one on my current Ext.

the coil will only produce the ammount of voltage absolutely necessary to to do the job, regardless of what the coil is capable of. and the truth is, that the stock coil never has to approach its maximum voltage potential. not during startup, cruise, or at WOT at 5000 rpm. and certainly not at idle....
