So on my way to work the other day and all a sudden there's a nasty grinding sound coming from my 97 runner. Pulled over thinking oh shit trannys going but when I pulled away again no noise. I get about 2 miles down the freeway and there it is again followed by a loud pop then goes away. Got under the truck over the weekend to check it out and notice tranny mount bolts are all only finger tight, got some chipped teeth on the flywheel and what looks to be a wear mark on the bellhousing where it looks to have contacted it. Question i have is could the mount being loose cause the flywheel to contact the bellhousing? If not what would cause this? Any help or ideas would be much appreciated thanks.
