Shocks are new 5100's all around.Oh man this sounds terrible!
I had considered doing Atlas springs as well, but after getting into all my work and not knowing future weights I found out that SD (10th gen) 250 springs ended up giving me the perfect ride... Except for the Bilstein shocks (junk).
If you really wanted to you could file a BBB? I did that with ATT recently actually, seems it was the only way to get them to listen. I have heard so many great things about atlas. Maybe they just screwed up and are super nervous to make it right? Although that certainly is NO excuse from a company...
Maybe I missed something, but are you also replacing the shocks at the same time? I think its always a good idea to do shocks if your doing springs. Unless theyre already new.
But now that I just saw pappa's post hahahahha...maybe theyre training someone new who doesn't know how to take orders correctly!
Yeah I've already cleaned this truck once of mice..... (PO hid it...) I can't find any obvious holes.On gross... Nothing I hated worse when a tech as doing something underneath and a big full nest vell all over your face... paranoid of diseases.
Hmm....for it to be in the B pillar I would first suspect some sort of hole in a grommet in the firewall somewhere, but they could also sneak up through some of the 'seals' on the floor. I'm not familiar with your specific year truck, but if theres any sort of openings at all.... Going actually AROUND the heater core is possible as well. Checking your cabin vent filter (if you have one) is a good idea.
