Ford Repair Questions? Ask a Mechanic for Answers ASAP
Thanks Steve. Wheel speeds being the same, which they have to be within specs is there a probability the drivelines were put back in a different location throwing the clutches off?
other that that Schucks offers their code reader for free and although I hate to drive it there I will and get back to you.
I would still look at wheel speed input, just because there are 4 new tires doesn't mean the 4x4 module is seeing the correct data, I would still look at this first, it is unlikely anything is put together wrong or out of phase, you might double check the u joint just to rule them out, sometimes they feel tight but are rusted tight and won't move correctly while driving. Any more questions just ask, Thanks Steve W
I see you replaced a pinion bearing in a previous question, did you reuse the same gears or was the rear end changed out or just the bearings and seal? Let me know, Thanks Steve W
Sorry just got in after working on it for the last while.
I don't believe it's wheel speed and realized a bit ago I forgot to mention other recent work. I didn't change the pinion bearing. I was hoping I could and we search indicates it's possible but it really appears you have to pull the whole rear assembly out and run it into the guts like you would a 9-inch but this clutch in everything crap really causes issues.
I RnR the transfer case and while I had it up I checked the typical back end roar. The pinion bearing was really loose so I did some research and decided I aintagoing to do it.
Both drive shafts were loose and the transfer case was replaced could there be a timing issue?
Also, I just gave it a run around the driveway and up and down. It's deffinitely shifting from hi to lo but not into 2wd. Right or left turns and it binds up in the front end.
I pulled the drive shaft to rear end thing after pulling the nut and then puting the two back on
I jacked it up on all fours (on wood chunks) and ran all four free.
As I recall there are three- two with sensors and a single orange wire secured which must be take out of the connector. Could you be more specific?
I removed the wire from the connector assembly and it doesn't lock up anymore! But what do I need to fix?
You need to monitor the front and rear driveshaft speeds and see if they match while driving, if they match, then it is likely the 4x4 module is bad, it should have a self test done with a scan tool to verify. If the front and rear sensors are different speeds, then look at tire size. There should be no more than 1 inch difference in circumference. Any more questions just ask, Thanks Steve W
Just figured out the tires might not be inflated propertly so I made sure they were all 35PSI. I then pluged the wire back into the connector and although it shows 4x4 on the dash and drops the gear ratio in low it's not locking in. Most likely module?
Disconnected, waited about 15 seconds, then hooked it back up.
4x4 low = the light blingks then goes solid like it should. Gears drop low like they should. no power to the front drive train. 4x4 high light in the dash blinks for a bit then goes out.
4x4 auto = light goes out goes back into high gear.
4x4 high = dash light in the dash doesn't work and it doesn't have power to the front drive train.
My wife drove it around today and she said it was locking up in the front end on tight turns. I questioned her (whoops!) but when she got it home I couldn't get it to lock up.
