CV Axle replacement

[tom4bren]

There's a way to get the computer to tell you which sensor is bad. I'll have to find the instructions - something about shorting 2 pins on the OBD II connector & counting the number of flashes of the TOD check light.

But go ahead and check all the connectors first & check all wiring near the exhaust for burns & shorts. Either of those can cause the computer to think you have a bad sensor.

The procedure is in this pdf file.

ok, I found code 31 is displaying. Which is shorted or disconnected coil wiring. Any idea where I should start looking for that?

[tom4bren]

IIRC someone posted that they had melted TOD wire insulation where it got too close to the exhaust. I'd start there.

[VehiTONY]

Well, I did find some wires near the exaust that had some heat damage, but didn't seem to be the problem.... In fact I checked all the connections on the transfer case that I could find with no resolve yet.

Yeah, I need to look under the shifter assembly. I have the same issue with my VX, and I would like to think it is simply broken wires as well. I had the TOD check light come on and the codes are front and rear speed sensors. But I cannot see how the wires for the speed sensors are anywhere near the exhaust, but I really haven't had time to crawl up under there.

In order to see the top of the trans, you have to undo the shifter from the side of the trans underneath so it can all be pulled up. I'm hoping to get to this on mine soon and with any luck, I will find the broken or disconnected wires.

Let me know what you find... Does your 4L work? Mine still works fine with the exception of the 4H not working. Wish I could manually engage that one.

I'll continue to look at everything and try to trace the wires back every chance I get but that will have to come in sperts do to lack of time and or patients. Besides i'm a little more worried about the front axles for the moment. Only the drivers side is bad but the boot on the passenger has a hole so getting that done is priority.

[nfpgasmask]

Yeah, same situation for me. 4LO works fine. It's just weird that it popped up out of the blue. Just driving along one day and it started flashing. This is why I suspect melted or disconnected wires.

Hey, I bought new axles for the front... Will be putting them on later so I'll have some pictures to post up here.

[VehiTONY]

Well it turns out that my axles both are stuck in the casing so have to wait till Tuesday to have the job done.

[Triathlete]

Are you replacing the whole axle or just the half shafts? Where are they "stuck"?

[nfpgasmask]

Yeah, you probably are pulling on the half shafts and you need to remove the large retaining ring. Are you stuck at the "green soup can"?

Bart

[VehiTONY]

How do you remove the ring?

[bartmanS4]

Pry it out with a screwdriver. It's a flexible split ring.

You have to clean the grease out first, so that you can see the ring.
Look all around for the join, and lift up one end with a small screwdriver.
Once you have it started the rest just flips out.
