05 Tundra DC - Vibration/rubbing????

Tundra Monkey · #1 (**permalink**) 10-05-2005, 11:28 AM

I have been noticing lately that there seems to be a rubbing/vibration coming from the truck. I have no clue what it could be. It seems to be cyclical, and occurs at various speeds but I notice it more at lower speed with everything off and driving straight. I can't tell if it is coming from the wheel or the drive train, it doesn't occur on every rotation of the tire but about every 5-10 seconds. I thought maybe it was a warped brake disc but that doesn't seem to be it. It seems to come from the center to left front of the truck, or at least thats where I notice it because I'm driving. I have listened for it both when on and off the gas. It is pretty subtle so that is why I am having dificulty identifying it and describing it. I have 10k KM on it now.

I gues my best way to describe it is it feels almost like engine braking but occurs like a disc rubbing the pads, but like I said its not in sync with tire revolutions. If I had to guess I'd say it happens every 5th rotation but may vary. I was thinking it may be something in the drive train too. Also it is a 4x4 limited but its not driven in 4x4, actually haven't tried it in 4x4 to see if it still happens.

In any case its in the shop next week so I'll have them look at it. Was just wondering if anybody had a similar experience or any ideas as to what it might be, it bugging the hell out me!!!! LOL

any correlation with temperature? Correlation with temperature and/or if engine is under slight load such as going up a hill with constant pedal feed?

I believe I've noticed this also. I almost get the feeling of front rotor vibration or rubbing, but haven't been able to determine for sure. Wonder how balanced the drive line is--if it's maybe vibrating.

There is often the possibility of defective wheel bearings. Yes wheel bearings. The front wheel press bearings, which are exposed to high temps also along with the rotor--

I don't think its a temperature or a load thing because it is accurs in all normal driving conditions.

As for the front rotor, bearings and possibly the balancing of the drive line, these are all reasonable possibilities I think from what I am experienceing. The weird thng is that it doesn't seem to coincide with tire revolutions ...which I would expect if it was bearing or rotor.

Think more about the temp part, I have had to brake hard a couple times from less than 60KM/hr to a dead stop, would that be enough to heat up the brake or bearings enough to cause damage. I would think not, especially from just a couple separate instances.

A front wheel bearing usually gets louder with speed. They will also change sound as you steer the front wheels, as the load changes on the bad bearing.
You might also look at the center support bearing for the rear drive shaft. I have heard these make very strange noises when the go bad. But many times these are more noticeable at low speeds.
