DW2018

thank you

Mechanic did diagnosis...they said they went though everything "easy" and determined there were no problems there-it was in the front end that it would be a lot of time in labor just to take it apart and get it back together and asked if I wanted to bother, this was last year and I said no so not something they were getting money from- and they are always booked so dont think its a money thing at all....also it was a one owner vehicle before me I bought it from a dealer with a 30 day warranty/over 100k miles and didnt find out the 4 wheel drive didnt work until a month later when i got my horse trailer stuck at a horse show... so dealer wouldn't do anything about it and I suspect original owner got rid of it because they busted the 4WD and knew it and know Im suspecting they knew it was going to be a pricey fix... just trying to figure out if its anything we can tackle on our own

When I turn the knob to engage the 4WD the indicator light indicates it goes into 4WD. However, the front wheels do not actually turn. Once the truck flashed a service 4 wheel drive message- but that was once it was not working for months with no message and message is now gone again. Took it to the mechanic they said- they went through everything and its in the front axle they would have to drop the axle and take it apart to figure out the specific part.... I am a bit confused what that means now that I think about it- it is a 2011 GMC Sierra 2500- it has IFS not a straight axle?
