I wish I would have gotten to this sooner.
So I used to have a rattle
and it drove me nuts. I thought it was my port installed roof rack, it was not. Turns out it was that my roof panel had separated from the bracing under it.
Put some dynamat type material and some sika flex 221 sealant. wow. night and day
its like a new truck inside. I also went to a new oil that smoothed things out and changed the transmission shift pressure to smooth things out.
so much nicer to drive. I just need to revalve my shocks to have less compression and I’ll be just about perfect for what I want in ride quality.
now enjoy something fun
