Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, I'm Cam. Please include all the details about your issue so I can accurately advise you. I cannot see your vehicle so please be detailed.
Did you try pushing in the plunger that the actuator pushes to see if that engages the front end?
this is not a manual actuator, so i don't know how i could manually push in the plunger
i did verify that the solenoid is extending when i disconnect it from the transfer case
The plunger from the actuator extends into the front diff and pushes a sliding gear on a fork over. USe a screwdriver to do the same.
so remove the actuator, then push the fork over with a screwdriver?
yes, see if the system engages.
will it be obvious what i'm pushing on? if so, i'll go try that right now
It is the only thing in there.
perfect.. i'll go try it right now
i depressed the plunger, but I could not tell if front diff engaged... would i be able to hear something?
I have to go and shovel my walk, I will be back in 20 mins.
ok thanks for your help
Unless you have results now? If not I will check back in when I get back in.
i just tried... no luck
i didn't hear anything engage... also had my neighbor verify that the indicator light in the cab did not illuminate
Ok, did the plunger go in about the same distance as the plunger extends?
no, it only went in 3/4"
the solenoid seemed like it could extend 1.5" when i energized it manually w/ 12v
Ok, try again but turn the front drive shaft by hand. IT may be that the gear is not lined up.
sorry for dumb question... front drive shaft is the 2" pipe entering the front diff from behind?
seems like i could only rotate that piece 1/4 turn
i can't remember... should it turn freely in 2WD? after you reply, i'll go check
btw, i am not on a lift... i'm just crawling underneath the car
I understand .It should turn freely in 2wd.
ok... turns freely in 2wd... i tried manually depressing the plunger w/ a screwdriver in both 2wd and 4wd modes and did not hear anything engage
Ok, then it sounds like you have a problem in that right axle tube.
however, when i switched to 4wd, i was unable to turn the front drive shaft
Ok, that is normal as the front drive shaft is engaged in the transfer case.
i'm looking for information on a right axle tube... do you have any suggestions?
What sort of info?
trying to understand what it does, how it may have gone out since last time i used 4x4, and most importantly, if this is something i feel comfortable repairing myself
ok, the front diff is open and the axles to the wheels turn all the time. Inside that tube is a sliding fork and gear. When you engage 4wd, it locks the 2 parts of the axle together inside and closes the system. If that gear is not moving then the 2 parts of the right side axle tube are not locked and it is not transfering the torque.
ok, i got it... i understand now, and i agree with your diagnosis
thanks so much for your help... i will definitely "accept" you!
