Front End Groan/squeak 2008 Gmt900

[Bish]

Just developed a groan in the front end. Sounds like a bad shock or a squeaking rubber grommet. Happens when I go over a large bump and it sounds like it comes from the driver side front.

 

Anybody aware of any tsb's for this? 2008 Yukon Denali. Thanks in advance. I know you may not be able to post the details but any info would be appreciated.

Follow-up

 

Just heard back from the dealer. They think I have a blown strut on the pass side. Can't find anything else. Had to order parts so I'll find out Friday if it is fixed. Those electronically controlled struts are not cheap either. Good thing for warranty! First real problem at 18K.
