Warning lights Traction Control and ABS

[JeepLab]

Ok, so here's what Ive done.

RK 3 - Link Front Rear Long Arm suspension.

Regeared to 4.56 gears

Adjusted the parking break

installed all new axles. Front and rear Yukon Chromoly axles.

The problem now -

My traction control and ABS lights are popping when i drive above 60 mph.

The course of action -

I think the alignment is off. When i turn the wheel i hear a thud somewhere in the nose of the truck, not all the time, just when its stopped. I used to think it was the coil over puck moving up and down on the shock. Im bringing the truck in for an alignment tomorrow. Ill have them tighten all the drag link suspension and do a 4 tire alignment.

with everything straightened out and bolted down tight, we will see weather or not my problem is solved.

[JeepLab]

Ok, its aligned. Problem not solved.

Gotta go a little deeper.

Only above 60mph? Have you done the obvious in checking all the sensors at the wheels? If this started after recent work, that is just the first place to check. Sorry if that's obvious and you already knocked it out.

Is this popping when you turn left/ right/ both?

[JeepLab]

Is this popping when you turn left/ right/ both?

only at high speed. Straight line, 70mph makes it pop, or if I'm on a jug handle on the gas it will pop.

What do the wheel sensors cost? Were these the same lights you got when the tire wore through the wire of the wheel sensor? Can we return the wheel sensors if that turns out not to be the problem?

the first step now is to figure out which corner the problem is in. Once I get to the bottom of that, ill start changing out the sensors. i have an appointment monday.

[JeepLab]

its the passenger rear. I took the axle apart from the truck to check the sensor and abs ring.

Turns out the abs ring was damaged somehow. the truck is in pieces, so i dont know if Ive solved it yet. I should have it back together tomorrow.

If you are following this nightmare, here is the most recent update. Yukon sent me a new axle all pressed together correctly.

We installed it without a hitch, and now rather than the abs and traction lights coming on some times, they come on all the time. I didnt make it out of the driveway.

I dumped oil over the berring before intalling it, so I may have splashed some oil on the sensor. Took it out cleaned it, put it back, same problem. Took it out again, more oil on it.

Im going to let it settle over night, since im exhausted. and fire it up in the morning. Hopefully this problem will be over.

My weekend Jeep hobby has officially bled into the week.

Heres what Ive figured out. We changed all the axle components and the lights came on right away now. Im thinking, I've taken this sensor out 20 times now, i must have just really broken it.

upon further inspection, it appears the tone ring is pressed in backward. Easy to overlook....The sensor does not overlook it. It freaked out right away. pics coming

[JeepLab]

Here is the shot with the abs ring pressed on backward.

Its got a wide opening on one side, and a narrow opening on the other.

I realized it when I saw how far past the ring the sensor was. My heart broke when I realized I had to rip it all apart again.

Pulled it out and had to cut the rings off. ABS ring, seal, berring,

Pressed it all back together and as far as i know, it all works now. knock wood. I didnt drive very far.

Dude...lights out now? Still? Been two days!

Dude...lights out now? Still? Been two days!

I only drove it for 5 min once i thought i fixed it, then it rained for 2 days, and I hate putting the top up. So she sits in the garage.

Now im gone for a week so dont hold your breath, Im pretty sure I fixed it tho, and this one goes down in history as one of the most difficult mods of my career. Not because of faulty gear, the yukon stuff is top notch.

I had gotten the axles about a year before I installed them, and they went thru a move from one location to another. In the box come 2 axles for the rear. They are in the box opposite one another. The end of one axle sits right next to the tone ring (abs ring) of the other axle. During shipping or us moving it, the one axle bashed the tone ring on the other, nothing major, but one tooth was damaged and the sensor would freak out at high speeds as the one tooth would throw off the sensor's math.

Then we did it again and the tone ring was pressed on backward. This i didnt realize until after install when the senor really went nuts all the time.

Mind you, everytime you take the axle out you are risking damaging the bearings that will make noise. Also you are spilling oil on the ground right where you are working each time.

So we put in and took out the passenger rear axle about 3 or 4 times. By the end, you are working in a puddle of oil trying not to damage the bearing....etc.

Im glad its over. I know everything about axles now tho.
