There is DIY on the forum not sure exactly where, but using the "search" will find it for you.
How do you know the canister is bad? What codes? Have you tested or replaced the purge valve at the canister, new gas cap, replaced old/broken vacuum lines, PVC valve/grommet, etc?
The canister should be replaced only after all the other things have been checked/tested/replaced.

Check your evap hoses up front. I was told i needed a new evap cannister also and there was a broken hose up front. I changed the hose and the engine light went away. These cars are old bro check your hoses amd get a leak test if you can. Mine was a 2$ fix yours might be also

Here is how I did it without messing with the rear hub and rear control arms, please refer to the diagram below.
I did not take pics, it was very dirty under there and dirt was landing on my face.
Once I had the car jacked up I was done in 90 minutes...

Once I had the car jacked up I was done in 90 minutes...
- Jack up and properly support the passenger side rear of the car.
- Remove passenger side rear wheel.
- Remove the rear suspension brace, both sides.
- Removed the 3 nuts that hold the canister and disconnecting 3 hoses and the 2 connectors.
- Remove the charcoal canister mounting bracket, 2 bolts on the right side of the assembly.
- Remove the 6 10mm allen head bolts that hold the RH rear drive shaft to the differential. Mark the alignment of the axle to the differential.
- Carefully push the axle outward and drop it down to the side.
- Remove the rubber band type hangers that supports the exhaust pipes. this will give you enough room to move the drive shaft a few more inches out of the way.
- Remove the charcoal canister assembly. It might take you a few minutes to fit it through the opening.
- Replacing the new assembly is reverse of removal, including removing the mounting bracket on the right side of the assembly.
- Torque the drive shaft bolts to 61 ft/lbs in a cross pattern

Thanks FrankT. I took some pictures and will post it for other people who are interested. My check engine light still came back after changing the canister. It looks like there is leak somewhere. My guess is the hose connecting to the gas tank.

update on code P0440: After changing the charcoal canister, the code came back shortly. I have had this code for about 2 years. Recently my alternator went out. I changed it and the battery was disconnected for a while to perform the job. After putting the new alternator, the code never came back. I have been driving for several thousands miles already. Not sure what the issue was.

Update: the code eventually came back a gain. Took it to lexus for diagnosis and they told me the rotary (overfill) valve on the top of gas tank leaks. I had 2 valves on the top of gas tank replaced and the code has not come back.
