Hello Fellow Patriot Enthusiats,
I don't wish to get in the middle of a spitting contest on this 'Hood Flapping' and 'Bonnet Flutter' issue, rather only wish to add what I personally observed at my local dealership earlier this evening.
After finishing a brief grocery run to my local Wal-Mart, I dropped in on my Chrysler-Dodge-Jeep-Ford dealership which is conveniently located across the highway from aforesaid Wal-Mart. Since it was after hours, I enjoyed the luxury of being able to walk the lot without needing to worry about being tackled by a hungry, overly aggressive salesperson.
On the lot currently were eight Patriots, seven Compasses & seemingly countless 2008 Jeep Libertys. The Patriots and Compasses were a mixed bag of '07s and '08s and I took the time to check for rear hood lift on every single Patriot and Compass on the lot, plus about a half-dozen 2008 Jeep Libertys.
What I discovered with my static tests confirmed what's been reported in this thread: the windscreen end of each and every Patriot's hood could be easily raised by hand by 1/2 inch or more. Similar static tests on both the Compass and the Libertys revealed no lift whatsoever, both model's hoods being solid and tight.
What does this mean? I can't say for sure, but I believe it's an observaion that should certainly be reported to Jeep engineering with the hope of learning whether this 'lift' is intentional or an unwanted, but unavoidable artifact of the coachwork's design because of constraints imposed on the vehicle's design and/or manufacturing engineers.
From what I observed and after inspecting the bonnet's hinge design with it raised, I humbly submit that the 'hood play' is a direct result of the articulated hinge's design and completely unrelated to improper adjustment of the rear under-hood bumper stops. Ratcheting the bumper stops up may appear to solve the problem, but improper adjustment of same is not the root cause of the problem .. if indeed it is a problem at all.
I will admit that I've never seen anything like this in the 40 to 50 vehicles I've owned in my lifetime, but whether or not this measurable 'play' at the hood's rear will eventually lead to premature metal fatigue and possible failure of the hinge itself is of yet unknown .. at least to me. In the meanwhile, I believe it's right and proper to be cautiously concerned about the hood's dynamic behavior and to bring it to the attention of Jeep's engineering & management hierarchy.
Finally, I'd ask all forum paticipants to remember that what we have in common easily trumps our differences.
We are a virtual
family so to speak, and I trust everyone will keep that in mind before becoming overly defensive or turning on the flamethrowers.
+ PEACE +
Irish Waif
