Hi all! I've done the search on this forum and actually crawled up under the truck to see about lubing the chassis and I don't see what the pics show on my truck. Did they seal this too?? The reason I'm asking is b/c I'm starting to have rough slow downs (not sure how else to describe it). This lubing job is often overlooked with oil changes. It's a 2wd. I've had a 4wd which had the clunking issues and this is not the same. It's a 2007 with about 7600 miles. Any insight would be appreciated!
