Hey folks. I've been investigating a newish clunk coming from the front end. 08 Denali 6 2 AWD. It's not the engine or diff mounts, already replaced those last year getting rid of the last clunk. It makes a big clunk when going into gear, or when I decelerate and then jump back on the accelerator, but it's worst when shifting down for passing. Feels exactly like a bad motor mount (and yes, I checked to make sure the new one isn't broken ). Dug out the GoPro and laid it under the front diff, while I shifted back and forth from drive to reverse. I'm getting between an eighth and a quarter of a turn rotation on the pinion as it engages. This seems pretty excessive to me. What do you all think.
I should mention, when I replaced the diff mounts last year, I tried to do a diff service, but the plugs are seized in hard. I even hit em with a torch. Which probably didn't help the fluid inside. Finally gave up. Oops.
I tried to attach the video file, but it's too large.
