Yeah, you're right. I couldn't make out the bolts from my cellphone when I replied earlier.

A full-float axle will have a bolt in axle shaft at the wheel. You should see the heads of the bolts at the center of the wheel inside the lug studs. If you have 6 lug wheels, you have the semi-final axle.

 

You can pull the diff cover to see if it has anything or if it's just an open diff.

 

that would mean oil out what is not planed atm, but i will try to fix that electrical issue and then jack the back up to check it. Thought it would be just visually visible so i can order the new axle sooner.

 

i located the problem to be the idle air valve, is it this one, the correct replacement?

It looks the same, but am not sure there were more versions...

Also can anybody help me to id and locate replacement for this temperature sensor?
It have three flat pins (for what 3?) and is on the side of apparently aftermarket cooler...



today i was trying to fix some wiring to the cooling fan and some other electrical issues.

 

today I've had finally little time to work on our Blazer again with my son.

there was a broken cooler cap, it was causing overpressure in cooling system.
We fixed it with hammer (it will get big alu cooler soon, probably)



and replaced the broken cap... I have had this on my vette and was happy with it through some rough testing conditions so i bought it for my Blazer too



we replaced the broken IAC which was causing our darling to idle too low when it was cold. Now it seems to be running fine, tad high though (1100rpm) but better then constant struggle with idle. The Check Engine keeps permanently flashing so i am afraid i have to replace the ECU as well... Well so is the life...





New air filter compared to old one...... Lol. It was just oil lump. Wtf.


this is only temporary solution as we plan to put a holley compressor on it anyway but i want to drive this big bad boy for some time during winter as it is SO MUCH FUN, especially with 2WD now.

And first lights come in... Our blazer will have lights on the roof and on where stock lights are on, but the bumper will be removed.
