Luke Posted July 13, 2005 Report Share Posted July 13, 2005 (edited) I'm going to take my truck in to have the front differential looked at. I just started a new job and I'll be commuting to work (60+ miles a day). I've noticed that this "Grawling" noise occurs under load at both low and high speed. I'm begining to feel it in the steering wheel and gas pedal. It seems to be worse in the afternoon on my way home (outdoor temp around 90), but just mild in the morning (45 to 55 degrees). When I go in to the dealer what should I have them check out? Should I have them drive it first? It sounds like the "Grawling" noise is common to these trucks. I knew it would happen sooner or later, but it still bugs me Edited July 13, 2005 by Luke (see edit history) Quote Link to comment Share on other sites More sharing options...
CoolBlueSS Posted July 13, 2005 Report Share Posted July 13, 2005 Tell them you hear a howling noise that gets worse at hyway speeds. Quote Link to comment Share on other sites More sharing options...
edessa Posted July 13, 2005 Report Share Posted July 13, 2005 You need a new front differential. I had mine replaced almost a year ago. Someother member had theirs replaced also. Do a search on front diff noise. PM me if you need any help. Quote Link to comment Share on other sites More sharing options...
Luke Posted July 14, 2005 Author Report Share Posted July 14, 2005 Will a bad differential cause damage to any other drivetrain components? It will be about a week or more (400+ miles) before I can get it in for service. Is there anything obvious I can look for without having to drain or take apart the diff?

StealthSS Posted July 16, 2005 Report Share Posted July 16, 2005 (edited) Mine is in, looks like they are going to replace it. I will know for sure Monday. Can you believe some dumb service writer tried to tell me the noise was being made by/coming from my trenz billet grille? I shut him up by asking him why I feel the whine through the steering wheel and brake pedal... Anyway, they paid for me a rental so I look like gramps going down the road...in my 05 LeSabre I think its gonna get fixed right-my dealer is usually good to me. Just fyi, Im at 4900 miles.

edessa Posted July 16, 2005 Report Share Posted July 16, 2005 (edited) It's like the bull they put out in a letter to shops, that the K&N filters affect the transmission. Edited July 16, 2005 by edessa (see edit history) Quote Link to comment Share on other sites More sharing options...
fordsareslow Posted July 17, 2005 Report Share Posted July 17, 2005 It's like the bull they put out in a letter to shops, that the K&N filters affect the transmission. <{POST_SNAPBACK}> I heard that. Something about the oil on the filters burning the wires on the throttle body and causing the transmission to go out Quote Link to comment Share on other sites More sharing options...
StealthSS Posted July 20, 2005 Report Share Posted July 20, 2005 (edited) Not p.o.'d _yet_ But today the svc writer called and said this to me, "Your truck is being finicky...we can't duplicate the problem...drove it 20 miles...didn't hear it...stay in the rental..." Oh, and they are still trying to say its my Trenz grille making the noise...if they say it again I will take my tools and remove it right there...then have Mr Knows My Truck Better Than I Do ride with _me_...he should take his stethoscope along, because I bet if he places the probe in on a hard surface on the firewall, or even on the steering wheel or pedals, he should be able to hear it plain as day. How the hell can it be the grille making the noise when it changes in pitch proportionallly to vehicle speed? I am not taking it up my six from these people...

oscareltemblo Posted July 20, 2005 Report Share Posted July 20, 2005 Well guess what my dealer srvc tech called he said the noise is regular drivetrain noise and told me to drive like that ,if it gets worse to bring it back in ..This is bull they should know these are common problems and they should have replaced my diff.

kaotik1 Posted July 20, 2005 Report Share Posted July 20, 2005 Not for nothing, but I think guys need better dealerships. I had my diff replaced the intermediate shaft fix then last week I brought the truck back for a slouchy trans, and wobbly mirror.. Then updated the trans, and ordered a new mirror just need to be painted and installed now. I have an appointment for next week. Quote Link to comment Share on other sites More sharing options...
