My Tire Pressure Sensor on a 2002 Jeep Grand Cherokee Limiter V8 L4.8 is broken and I found a replacement one new from Schrader for $50. And I have a few questions.
1) What is involved in changing the Tire Pressure Sensor or should I have a shop do it?
2) Is the brand Schrader a good one or should I go with the one from JEEP for $300?

Schrader makes 99% of the OE fit TPMS sensors anyway so they should be fine.
The sensor needs to be tested before installation. The tire needs to be dismounted to install the sensor, then all four sensors need to be re-programmed. This is best done at a shop or dealership with the necessary equipment.

The sensor (and your vehicle DOES have pressure sensors, not just wheel speed sensors) were either already supplied to Chrysler by Schrader or by Siemens, depending upon the year. Schrader has replacements for both theirs and the Siemens model, and can be trusted. I'm pretty sure that your Jeep came equipped with the Schrader SB-20028 from the factory. There's no need to pay the dealer more.

the only tire pressure sensors I have dealt with were on corvettes. They were strapped to the inside of the wheel so replacement had to be done after removing the tire from the wheel. I sent the wheel and tire along with the sensor to the tire store for them to do it because we didn't have a tire machine that could handle corvetter wheels and tires. Some vehicles don't use an actual sensor. They use the wheel speed from all four wheels to determine if one is spinning slightly faster than the others. because the lower inflation will cause the tire circumference to diminish. the algorythm notices the higher wheel speed in coordination with the engine parameters to determine that the wheel speed increase is not due to loss of traction during acceleration. But since you say you have found a replacement tire sensor, I'm sure you'll have to dismount the tire to replace it. The TPM system consists of four battery powered, water resistant, radio frequency signal generator sensors and a receiver with self diagnostic capabilities. A sensor is mounted on each wheel on the back of each valve stem. The valve stem and the sensor battery are integrated and are not serviceable. The receiver is located over the LH rear wheelhouse.

I would go with the one from Jeep as you don't know if the Schrader one is compatible with the Jeep system.

you have to take the tire off the rim to change your sensor so unless you have a tire machine in your garage...you need a shop to do it
as far as the part just make sure who ever does the work programs your sensor to your vehicle
