When I was down on Tobacco Road twice last month, I got bug splats!

 

just going down the road and ,

 

Congrats on reaching 200,000!

 

Yes congrats on the 200k !
Im new to this car so is all the road surface noise normal? I know what a bad bearing sounds like on most veh Ive worked on so this noise is bothersone. Ive driven 07, 10 Impalas on the road and its similar ridiculous road noise.

 

I did my rear drum brakes. I thought the "old" 2006-2009 system was a pain, with the right tool they were easy! The 2010-2011 looks like the old fashioned "Chrysler-Jeep" type with spring & cup hold downs, but you have assemble all of the return springs and parts at the same time and then apply the hold downs. You need at least 5 hands to do it easily.


CURED the brake judder. I noticed that the leading edge(top) of the trailing shoes (e-brake side) was worn down twice as much as the bottom. I am guessing that made the drum think it was out of round. Spinning the wheel made a sush-sush sound that is gone now.

Makes me wonder.

New shoes from Ebay $15, new wheel cylinders from Ebay $20, new hardware from NAPA $11. Finally used my one man brake bleeder ($7 from Harbor Freight).

Now I have replaced the entire brake system, save the calipers, and all 4 hubs. NO brake judder for a while.
Got LCAs and sway links in stock, waiting to find sway bushings on sale.

 

You may be needing hubs front and/or rears.

 

This doesnt sound like typical bearing noise, its not a roar and there is no change in pitch when I throw it side to side at criuse speed. I get now something about the hub core assy. Is a vulnerable design (lack of a better word) youre right, it dserves more attention that this could be what begins the brake scoring an eventual runnout problem outside the hub. I know wheel lug torque if done wrong can start the same runnout problems either sooner or 1000 miles later.
I notice my old oem style rotors are not machine balanced, Hubless rotors generaly aren't but these are heavy as heck, seem much heavier than f150 or crown vic p71rotors of the same diameter.
time to search hub assy.brands for best quality :o)
my links came in today but im going to hold off pulling the wheels, may be ordering more parts asap

 

OK, ignore empirical evidence. Either hubs or tires.
Hub/bearing are not news on this forum! The most referenced problem I can think of. Give the SEARCH box a try, it's good.

 

I agreed with you on such a studious level you should feel empirical, if you comprehended my overall response. Im quite famliar with search functions DB, again though youre right, the gatorbacks may not be helping.
This isnt the correct thread to discuss in depth the hub design faults as they pertain to this bastarded heavy bodystyle on the Delta chassis. My direction is conceptualizing an improved part either drawn up by us HHR fans and hired out to a machinist OR possibly using GM (or other) parts bin to find a more durable hub/bearing/spindle for a reasonable cost to a modifiers budget.

 

Made room for the new arrival (red SS panel) and sold the V8 astro today too. john
