2007 suburban

[traveus]

I need a little bit of help. When I start my truck up in the mornings I get a little rattle. Only does it when it's cold. I've tried recording it, but you can't hear it on the video. Just asking if anyone on here has heard it too. It's hard to say exactly where it's coming from, but I would say more from the trans area. Any input would be greatly appreciated.

Also it doesn't get louder or go up or down when driving.

By your description it sounds exhaust related. Maybe the internals of your catalytic converters are falling apart. The cats are somewhat near the trans.

Never go to macco worst mistake you could make. I own an auto body shop and i hate fixing their **** ups half of my customers come from macco lol. As for your issue had the same problem on mine for my 2007 suburban lt 1500. I really needed to change my rear rotors and pads and grease up the pins in the brackets for the rotors. Remeber the truck has grease points and they do need grease once in a while i have a 4 inch lift kit also on 33s so i feel the struggle
