Replying to: doctony (Mar 29, 2007 2:02 pm) You are considering your 3rd 300? I would have avoided DC after the first no fix. I guess I am not very loyal. I have owned 2 chevys and one DC.

Replying to: batista (Apr 10, 2007 4:14 pm) Further, as the model years went on [2006 model and then the first 2007's], the problem became much lessened and who is to say what design modifications were done when the 2005 models showed such a heavy propensity for the 'very' discernible right hand pull, AKA 'crown sensitive' issue. I tried a 300 C 'Hemi' V8, late 2006 model, and the car was smooth and straight. Problem is when you make the move to the 'C' class V8 'Hemi' 'and' you want the AWD, well, the difference in trade-in plus up-front cash layout for the V8 Hemi with AWD can be considerable! But there are always deals or specials here and there or in some cases low mileage 'C' class vehicles available [including demo types] and the savings can be equally considerable. Sidebar: I really like that "magnesium pearl" paint scheme! As most know, including myself, when you buy brand spanking new, you 'pay' big too! And there IS great truth to the axiom that the moment you drive off the lot with a brand new vehicle, thousands suddenly disappear in almost instant "depreciation" because even after a first owner driven 100 miles, yeah, 100 miles, the vehicle is suddenly "used" or, as they [read: the dealerships] say today, "pre-owned", not to mention getting banged for the taxes! But that's another thread where the owner gets the hit for the trade-in/trade-up and then the same vehicle is subsequently sold for thousands 'more' than when the owner was allowed for the trade-in! Akin to the 3 or 4 thousand dollar 'detail job' so to speak. Let's face it, dealerships are in the business of making a profit any way they can! My gripe is having to deal with the bugs of a new model and then doing the up-trade thing for what was originally a 'known' [witness the 2005 TSB] problem but explained away with such terms as, you guessed it, "crown sensitivity" or, get this one, "overly sensitive tracking issues on 'certain' [emphasis mine] roadways" passed off as "the nature of the vehicle" with the word "vehicle" no doubt duly substituted ... for the word "beast." Doc Tony Hey! There's always the lottery! |

There are two issues here. First issue is the incorrect jigging of a number of early C300's. This is a genuine manufacturing flaw & it is partly corrected by the offset bolt bandaid. Depepending on the magnitude of the jigging error, the offset bolts may or may not correct the problem, but the chassis fault itself cannot be fixed. Second issue is crown sensitivity. This results from a deliberate design feature that is intended to give the front tires more "bite" in cornering & provide reduced understeer and sharp steering response that is normally completely absent in large heavy cars with long wheelbases. The front end geometry is similar in concept to that seen on a road grader -- the front wheels lean into the turn as they are deflected right or left. This greatly reduces lateral tire slip and sharpens steering response. It also introduces a pronounced crown sensitivity -- it is neither a manufacturing nor a design flaw and cannot be removed. It is there for sure on a crowned road, but takes only a little steering pressure to correct, and on flat roads it is absent. I quite like the sharp response -- the car has amazing right-left transitional response & tracking despite its 4,000 lb weight, slow steering ratio and 120 in wheelbase. My 300C is enormously more agile than my 300M ever dreamed of being. Chargers have exactly the same geometry & have identical steering response. Some folks don't like it -- so be it. I'll keep mine, thank you very much

Replying to: brit5 (Oct 03, 2008 6:15 am) You have to move the "rack" and resecure it with new bolts. I found the TSB myself and brought it in to the dealer. Wheel alignment guy said he had never been shown thyat TSB before. He proceeded to do mine and we road tested the car. I now have 62,000 miles on it and it;s still steers perfect. After the first wheel alignment and nothing had changed, the dumbazz Service Manager told me that they were made to pull to the right so that in case of a medical emergence the car wouldn't drift into oncoming traffic. I informed him that he had a mental problem and should see a psychiatrist ASAP. lol |
