Just a follow-up to my previous string on lubricating the suspension...
Here are the suspension bolts that I removed because they would not accept grease.
Note that they never had been greased by the factory and the bolt grease hole was completely blocked by rusted crud. No wonder my grease gun wouldn't work.
I probably have 8000 miles on the rig and although I see some wear on the bolts,
I think I caught the problem early enough. New toyhauler owners beware and check to see if your suspension has been lubricated at PDI (Pre Delivery Inspection)
