Hi i have a 2003 Montana and it sat for about a month, now i drive it and wow such a high pitch squealing sound. only when tires are rotating. now the brakes when depressed or not do not make a difference. it does not make the noise at all in reverse, if I make a right turn it goes away , if i make a left turn it does not. when i drive straight it is mind blowing loud pitch. steering does not shake. van does not pull to one side or other. when in neutral and engine not engaged it still make the noise. but when sitting still and reving engine it does not . only when moving those tires. axle what ever lol. so now what do i do lol buy ear muffs .lol kidding
