Clunk advice

[Clark W Griswold]

I have the clunk. The driveshaft has been greased. A shop has replaced front outer hub flanges. This clunk is clearly the front axle rotating when I go from R to D. The clunk also happens while driving if I take my foot off accelerator then back on.

My question is from my (very limited) knowledge the front hub flanges should have addressed this no?

the splies that interface between the CV axle and hub flange are worn due to age and miles. You can replace the hub flanges, but ideally replace both CVs and flanges to make it back to no clunk at all

Yeah; both the CV axle splines and flanges wear. You need to replace both. Make sure to properly torque wheel bearings as well.

Ok understood. Thanks. Weird that the shop did not do both.

Yes, both need to be replaced at the same time. How many miles on the vehicle?

I would check the condition of your diff bushings while you are at it.

Is this the big clunk when shifting between D and R, or a soft one when releasing the brake pedal from a full stop?

Make sure to get OEM CV axles as well; the aftermarket ones wear out prematurely from what I've heard.

In my search, after replacing anything that was worn, which for me was only diff bushings and sway bar bushings and links. it was rear brake pads and a proper brake bleeding that took away my random clunk after pressing on the brake stopping and then accelerating. The bleeding with new fluid did more than the pads in my case.

Sorry to bring back a three month old thread but I have this issue and was doing some research. I have new CV axles with no play, and my drive shaft is greased (as of today).

I was inspecting my diff mount bushings and there's no sign of wear or cracking. They appear to be in good shape but I'm not 100% sure, i saw another thread of people discussing the bushings and it seems like some replaced them and found out that it wasn't necessary. I don't want to spend the money for no reason, is there a good way to check the condition of your bushings aside from just looking at them?

Crawl under there while someone switches it in reverse to drive back and forth. I replaced all three bushings on mine, probably could of got away just replacing the front one on the cover.
