So, the front end of my 07 yukon xl denali has this horrendous squeaking noise anytime you drive over a bump. My dad, who is a mechanic, said it was swaybar bushings, but we've lubed those and checked and checked, and I don't see how that is causing this problem.
It's not brakes, it has to be some suspension component.
I looked at the front shocks, and they are Delphi brand, part number 1579972(i think). These are not factory shocks are they? This thing has 130k miles on it, so I'm thinking about replacing them anyway.
The rears are also Delphi, part number 15869658. They look like they have the right connectors and plugs to work like factory, and I've never seen any suspension dash messages, but I also don't think I've ever heard, or felt the compressor run to level the rear. I was under the impression that only AC Delco made replacement shocks that actually functioned as designed from the factory. All others just have jumpers or whatever to spoof the car and are just passive shocks.
I don't have any idea what was done to this thing before I got it, so could these shocks have been replaced with passive stuff and spoofers?
I know it's going to cost about $1000 in parts to replace just the shocks and I'm considering it, because I'd like to keep, or regain?, the factory functioning suspension.
I believe Ac Delco part numbers are 19300039 for the front and 19300072 for the rear.
I'd like to do this as inexpensively as possible, but I'd rather spend a little more to retain the factory functionality. I've looked into the Arnott shocks, and I know Bilstiens have a good reputation, but I'm pretty sure they are just passive shocks with spoofers... which is not what I want.
Anyway...any got any good advice?
