Put a jack under the engine. Loosen the upper engine mount bolts and lower the engine until you have enough clearance.

SOURCE: do 4runners crank pulleys go bad
Yes, in most cases you can. The crankshaft pulley is bolted to the front of the crank shaft by either 1 large bolt and thick washer, or by 4 small bolts around the edge of inside of the pulley, depending on model.
Remove all belts that are driven by the crankshaft pully and then grasp the pully to see if it is loose in some way.
To remove the large bolt(if that's what you have), will require the use of a strap wrench which can be gotten for the free loan-A-tool from Autozone.
Only if the end of the crankshaft was damaged in some way would you have to replace the crankshaft.
If you would like to contact me again about this or other problems, feel free to do so.

You will have to brace the crankshaft somehow, either by way of the flywheel, or the pulley. The trick to getting the bolt to break is "heat". Propane will sometimes work, but it's generally not hot enough. You want to get that bolt glowing if you can, and hit it with air impact then. Be careful not to burn yourself!
I hope this helps you, and I wish you luck on your repair.

Remove any oil or water on the idler pulley and keep it clean.
If the old timing belt is being reinstalled, make sure the directional arrow is facing in the original direction and that the belt and crankshaft gear matchmarks are properly aligned.
On 2S-ELC engines, make sure that the Matchmark on the oil seal retainer and center hole of the small hole on the camshaft timing pulley are aligned.
