Lights on dashboard are flashing

[TheThreeFs]

Hello everyone,
So I had to replace both of my CV axles and one of my hub assemblies. The axles were really jammed in there and I had to smack the hell out of both of them to get them out. I reassembled everything and the car drives fine but now it won’t go into 4WD and cruise control doesn’t work. I’m at a loss as to what it could be. There are two lights flashing on the dash as soon as the car starts, in park, in drive, always. They don’t go off at all. ABS sensors? Front diff actuator?

Only thing I can think of electronic in that area is wheel speed sensors. One on each spindle. Might want to check the one you removed for the bearing swap.

Awesome. I will check both of them. Do you think that beating on the axles to get them out could have affected the front diff actuator?

Just curious, but you DID replace the axles one at a time, right?

Interesting. Curious why that would matter, not that I have to replace my axles yet. Also, did you get axles with/without abs or would that be part of the hub assembly?

Abs sensors are part of the hub assembly, and if both axles are removed at the same time, you lose the timing or alignment on the differential (not sure my verbage is correct here) and it won't engage. I was instructed to do axles one side at a time unless you're replacing the differential.

I've had both axles out at the same time more than once, the last time pretty recently to gusset my spindles and control arm cam tabs. I don't see how this would cause an issue but I may have just had luck I suppose.

Yes I did. They were a real ***** to get out though. Out of curiosity what happens if you replace them one at a time.

So it turns out it’s not the ABS sensors. I’m thinking it’s the front diff actuator. I must have damaged it when replacing the CV axles. How hard is that to replace ?

I've never heard of this from a CV swap. Following to see what you figure out.

Me either. That’s why I’m perplexed. I swapped them out a few years back and the outer boots tore again so I had To do it again. This time I really had to beat the hell out of the passenger side which is The side that the actuator is on. I’m wondering what I’ll find when I get it off. I just don’t know how exactly to remove it.

I've been looking thru my search history for a few days and I can't find the page I was reading when I was researching axles. I can't remember if I read it on here or on another site because that was around the time I did the ECGS bushing on the driver side, but it was pretty specific as far as only changing the axles out one side at a time unless you were planning to change the diff, something about losing timing on the actuator which would make the truck not engage 4wd, I can't fully remember what it said, and now I can't find it either. Probably not so much you were lucky as I may have misread something, I'll keep digging...

I didn't see any trac or brake lights lit, so I figured it didn't have anything to do with abs. I don't believe the abs has anything to do with the engagement of the actuator. I have read about several stuck actuators, not had to change one out yet

For future reference, look for OEM axle-popper forks...life savers... everything else is just the hard way to do it.

I should have bought these before I attempted to get the axles out. The pry bars just didn’t work.

It’s a pretty tight spot. I might have to take off a bunch to get to the actuator. What a pain. Was hoping someone has removed/replaced it.

Does anyone know what position the actuator on the front differential should be in when in 2wd?

 

[TheThreeFs]

So I did some research about the front differential and the ADD actuator. I figured that it’s possible that it could be stuck in between locking the front axles and letting them spin freely so I pulled the ADD actuator out of the front differential and checked that. The ADD actuator was all the way to the right which from my research means that it was fully disengaged. The lights on my dash are still flashing and I’m at a loss as to what to do now. The CV axles are doing well in there. I do remember though that when I took the driver side off, put the new axle in and then took the passenger side off and put the new one in. Then when I went to add differential fluid I pulled the driver side wheel off and found the axle driver side axle not all of the way in so I pushed it back in. Could that have done something? I’m at a loss of what to do now.

Btw, I’ve never touched anything on the transfer case and according to my cheapo code reader my car is not throwing a code

Anyone?
