Go back and tell them they did something to your truck as it's not running right now. Have them scan for codes. Maybe the part they installed, the pulley sensor, was bad? Check the spark plug wires. Make sure they are seated properly. Run a scan and see what the status is on your O2 sensors ~ as a side issue.

They've put back the old crank pulley and it runs with no check engine light but the shake is still there ????

Sure you can. It just depends on how "good" the shop is at diagnostics. Sounds like you need a new Harmonic Balancer. When my Harmonic Balancer went bad, my X felt like it had a flat tire. They may have simply used the wrong part. Are there any codes generated?

Dude, you need to go back to who did the work. In fact, I'd have called and had them tow it in. They need to figure out why it worked before and not after. High possibility they'll end up covering it.

Go somewhere else, all expense will be on you.
