05 tahoe laundry list of issues

[Projecttahoe]

So just to check off some more fixes on the cheap tahoe i picked up , these issues existed before purchase , for some insight into all the issues I get a service tire monitor light (not too concerned because i ended up putting on wheels from a 2014 silverado) , service stability, service airbag, and a service 4wd light. Now with the mileage being at 274k its definitely possible these are all separate failures, but could any of these service lights be due to a related issue?

Check both front wheel hub bearings for play and any damage to the ABS sensors or wiring as well.

Get an advanced code reader on it and see what codes are setting the error messages.

my "service 4wd" sign came on thats when the tranny started having trouble and a month later i lost the torque converter and possibly need t6o rebuild tranny

I'll try that better code reader that has more functionality ,the hubs seemed fine i just finished front end work a few days ago tie rods ball joints ,stabilizer struts, and bushings and a new cv axle on driver side. The service 4wd has me leaning more towards the enabler motor , its stuck in auto 4wd and will not let me change to 2wd , 4hi or 4lo, knock on wood tranny has been okay

See what code is present for the 4x4, too. Here's a no-cost test for the dash mode switch:

Also there is an important body ground to clean, it's right behind the left front tire. Two bolts there with two or three grounds to clean.

Like @Fless said, also check ALL grounds: https://www.fixmyoldride.com/Chevro...e7e5cd24ed24635&at_ab=per-2&at_pos=3&at_tot=4
