Another question that will probably be considered dumb. I get this squeaking sound from my front end all the time now. I don't know if its a spring or the motor mounts.

When I go over a speed bump dead even (front wheels hit at same time) slowly they dont squeak. When I go over this particular speed bump that is at an angle and it rocks the car left to right twice, it squeaks like hell. Also, if I'm holding the wheel while taking a long turn and there are variations in the road surface while making this long turn, such as manholes or potholes it will squeak. Also if I'm going in a straight line at any speed above around 15MPH, put my hand at 12 o'clock on the wheel, and jerk it back and forth between about 10 and 2 o'clock really fast, it does the squeak when the car is going back and forth, in both directions.
The fact it does it when the car's weight is being shifted laterally (as opposed to up and down when i hit speed bumps evenly) makes me thing its the motor mounts. But I have not clue, just guessing. Figured the pro mechanics here would know

V has 100K+ miles

I'm getting Eibach springs here in a week or two now that we sell them through where I work, so I guess I'll find out if its them in the near future, but I'd like to know ASAP.

Thanks guys

Check the sway bar bushings.

Pretty sure motor mounts don't squeak. Not sure if the springs would either, but a bushing would be my first guess.

I agree. Check the sway bar and its mounts. Driving over a speed bump at an angle twists the sway bar.

yeah i had motor mounts go bad on my old silverado and it squeaked as a result but ok sounds good ill check that out when i move into the new house in a week or two that has a garage (two car = win) :) what kind of grease, like WD40 or some kind specific non-spray grease?

anyone have procedures to do this? sadly enough, unlike every one of my trucks and cars ive ever had, i dont know jack about the V :( knew the other cars like the back of my hand under inside and out. if its in the FAQ a link to that would be amazing!

Thanks for the thoughts so far though.

^ PS this question is assuming there is a sway bar elsewhere besides over the motor, such as under the suspension towers or something

bump for answer^^^

listening to it today, it is definitely a metal sound, a very metal sound, if its still bushings ill try to do it in a few when i can. but above question needs an answer. yes i know its a stupid question too

The bar over the engine isn't a sway bar. Thats just a strut stabilizer. The sway bar is a bar that bolts to the front cradle and then bolts to both lower control arms. The rear also has one and mounts in the same fashion as the front. The are kind of under the car but kind of not if that makes sense. I have never had to grease one but I would think WD-40 wouldn't last that long. Try to get some grease for bushings if you can, if not, I would just use a small amount of multi-purpose grease. There are pics of peoples sway bar woes on here somewhere that have good pics of the front mounts and were they are located. You can see the front mount easily with the front wheels removed. They sit forward of the strut on the cradle itself.

But as you said if it sounds like metal, I dont think it would be the sway bar bushings. Noises can sometimes be deceiving though. I would just check anyway. Its not hard really. I dont know were the metal on metal sound would come from. There are a lot of things it can be without hearing it or seeing it in person.

any kind of axle/bearing grease will work....wd40 wont last long....and if you say it's a metal sound....grease isn't going to help anything...you need to take the tires off or put on lift...there should be some evidence if you have a metal to metal rub somewhere...if you have a suspect spot...paint it with some white spray paint ....drive...and see if it wears or tranfers


edit: never mind I said basically the same as 154:thumbsup:

What I was referring to actually is a wearing of the sway bar bushing. It requires a total replacement. Greasing it won't help. Though, it'd actually sound a bit more like a loose rattling/clanking over rough/uneven surfaces, more so than a squeaking...

But not sure if it'd be metal on metal like. I'd check the sway bar bushings, anyway, just because it's so easy to do and, if it looks like it should be replaced, it won't be costly or time consuming. And, who knows, it may sound like a metallic rattling to you. Good lucks.
