yeah, age and repeated heat cycles on them will degrade them over time. i compared my original to a fresh one doing a test to pick up a razor blade for a utility knife and it was clear the old one was way weaker. shows up in the response time as the tone wheel tooth passes the sensor.

Would be interesting to compare the two signals on an O-scope.

yea a setup with a tone wheel on the bench would allow for seeing them side by side on a 2 channel scope.

I guess with all the miles and years, mine should be replaced then, but the truck is running like a top. Very responsive and good power, so I'll be in the "don't fix what aint broke" camp, lest I go broke.

Had it not been suggested to me, and going thru the effort to get the tune dialed back in, I would have never thought it could be an issue. The sensor I pulled out was weak compared to the new Cummins sensor, it was the OEM one. When I compared it to the NTK, that one had less magnetic strength compared to the original ones. After seeing that, it made sense that they gave me problems upon install.

both front bearings swapped, found a sticky ds caliper and a stripped slide bolt mount hole in the knuckle. this causes the retaining spring to dig into the rotor. nice. if i i c comfortably helicoil the hole, will buy brakes for up front. if not, will switch to '03 dual pistion setup.

picked up a set of ngk plugs, will do those sometime this week, expecting to find a stripped plug hole..

also going to revisit the 190* stat swap.

I know Steve, but 99% don't ship international, have tried for maybe 20 times, by chat and mail, different yards.
Thing is they all back out if you throw part numbers and ask for pictures before sending.
I've read so many times they send wrong part numbers, same thing with junkyards over here, and i can't return them because of time spend and cost, ( USA to Netherlands and back again ).

I have a shipper in Kent WA 98031, this is a Dutch family who lives over there and set up a shipping line to the Netherlands.
Spoke to them, and if delivered to them, they send the parts over, no problem, he will even check if they are the right parts or part numbers but he doesn't come in between if the parts delivered at his house are the wrong ones.

So i gave up on buying used from junkyards in the USA.
