Daughter was complaining that her front brakes were squealing and rear brakes making a "funny noise".
I went out this Saturday morning to investigate. Rear pads worn down to steel and one of the rotors stuffed. Fronts almost worn out.
A quick trip to Napa and grabbed a rear rotor and a couple of sets of front and rear pads.
All fitted up nicely and even managed to rotate her tyres, top the oil up and do some other minor maintenance. She had been out bush bashing and some how ripped the side step from its mounts. It was still sitting there on top of all the mounts, but the nuts had pulled through. Luckily it didn't end up coming off along a freeway or something. Spent a bit of time straightening it all up and rebolting it all.
OK, on to my 2010. The rear CV on front drive shaft was stuffed. I only replaced it a while ago, but this one was cracked right through on both sides. Bolted the new one in from Rockauto and all good again.
The clock spring has been giving me grief. Airbag light remains on now. I put another clock spring in from another Jeep. I checked they were compatible and it fitted perfectly and had the angle sensor etc.. However, the squib B circuit was open on this one as well.
A good way to check the circuits is to put a 3.3 Ohm resistor across the pins on the black and yellow plugs. These plugs normally connect to your airbag and the system is constantly sending small signals through the clock spring and to the airbags to check everything is fine. If you go over 8-10 Ohms, the system will report a fault and throw your airbag light on.
So, you need something like JScan. Go into the airbag section and select the Squib pids. You can then see what resistance the circuits are reading. I could see squib A was fine with a reading of around 3 - 4 ohms. However, the quib B circuit was playing up and rarely went under 8-9 ohms and mostly stuck at 10 ohms which is apparently open circuit. You can turn the clock spring a few rotations each way and see if the coiled up wiring in the clock spring is giving bad readings. Both my clock springs were acting up when i rotated them.
So... only thing i can do is buy a new one. I've ordered a middle of the road one from Rockauto. Mopar is now over $500, but i got one for $250 with built in angle sensor and warranty. I didn't want one of those Ebay cheapies.. Too risky. Its on its way, so hopefully she will be problem free again.
Cheers,
