Greetings. Am considering purchasing a 2005 Landau 2450DS but after test driving it noticed a whine under the hood at approx 60 mph. Backed off to 50, no whine. Not sure I like this, and want to ...
In the past some MH's had noise made by the grill. I'd think if it was an engine made noise if you brought the rpms up to the same as they were when it was going 60 the noise should again be there. This wouldn't happen if it's drive train noise though.
