did you heat cycle them 3 or 4 times? Did the installer test drive the vehicle after install? I would go get it checked out.....JMO

Make them fix it...they should back up their work. I just had my 3.73's installed Aug 22nd. I asked my installer about whine and if he guarantees there won't be any. He said there's always a little whine if you really listen close (had me worried). Thankfully, I have no whine. Love the gears.
