Hi, I've got a 2000 Toyota 4Runner 2WD that clunks when I put it in drive, reverse, or switch in between the two. I got underneath the vehicle and had someone shift the vehicle, and it looked like my drive shaft was binding up. I don't notice any play in my drive shaft, but I hear 'Yota's have issues with the drive shafts. Just wondering if anyone else has experienced something similar, and might be able to tell me what to look for?
