Took the suburban to the dealer yesterday for a coolant flush and the passenger airbag recall.
Of course with a 160k mile truck they gave me a laundry list of repairs, most of them were minor leaks on various lines. Not surprised on those, but what I wasn't expecting is they mentioned the front sway bar links were completely gone. At least that's an easy DIY.
I've had the truck 6 months now with 100s of miles logged on mountain roads and I haven't noticed "excessive" body roll. Maybe it's just perspective as my previous vehicles were smaller and sportier and I expected the Suburban to have extremely boaty handling.
