Anyone had luck replacing their camshaft position sensor? Or are they all a real SOB to replace?
I've swapped a couple out. It can be a pain, especially with older sensors that seem to expand ever-so-slightly. Have to remove the serpentine belt, and you can reach down in there to unbolt it, or it might be easier removing the splash guard, and laying on your back to reach up to undo the small bolts.

If it twists you can work it out. I had one that was seized in there and I had to attack it with long/skinny vice-grips. That was a pita.

Mine wasnt too bad. Take the intake tube off, and yoy have access from abovr to pry on it with a really long screw driver, as well as the bottom. I also used a pair of 90° pliers to help get it started. Once it starts to come out, it just pops the rest of the way.


I replaced front rotors, no more brake shudder coming down from highway speed. 127k on the original rotors and still plenty of meat if i wanted to turn them.

Lastly...anyone habe thoughts on the Naviks video in motion modules? Yes its expensive but the factory h/u does everything i need it too. Have another 2000 mile road trip comjng up, and having the unloxk would be nice

I had the harmonic balancer off and I could get it to spin, but not come out. I was worried about breaking the tab off or having to drill and tap into it with a slide hammer. That method doesn’t work. I’ll give the prying and 90° pliers a go after a dosage of Kroil.

I've still got the JVC dvd unit from my Sierra, sitting in a box in my basement. I'd consider using it, its just adapters id need BUT the big thing is i dont want to give up my XM radio, and i cant get the XM tuner that works with that unit anymore.

By the time Im in a new unit and all the stuff still needed, im way more then the Naviks unit. And honestly for me, the factory stuff is working just fine for me
