2011 Front Suspension noises - Question

[508gm1]

Hi everyone,

 

I have a 2011 Sierra extended cab truck. If I leave the truck parked for more than a few days, there are grunting noies that comes from the front end of the truck. It is most noticable if I am turning sharp over uneven pavement. It seems to settle down over a few kilometres of driving. Anyone have any suggestions?

 

Cheers, Brendan

if you can duplicate it take it in ,,,if not ,wait till you can

 

i personally think something is dry and MAY need a shot of grease but its not your problem and just take it in and say NOTHING what you think,only what its doing

 

if it takes the shop foreman sitting beside you while you duplicate it ,then thats what you ask for ,

I had this problem and it was in the rear. Its a typical GM issue "Leaf Spring contact". Its when all contact points hit and the leaf springs make noise. I went to the GM dealer and they put this grease on it but they say its a band aid as GM has yet to come up with a fix. So every oil change they slop more grease on it. But one dealer was trying to get out of it by saying it was KROWN fault for undercoating very liberally. BS its just rear end noise. But I found a good dealer who understands.
