Thumping noise coming from the front end

Hi,

I have a '93 Geo Tracker that suddenly started
making a thumping or clunking sound. On Sunday
night I took my Tracker out to do some some
shopping. I hadn't driven it in over a week, I
think. Anyway, as I was driving up the street I
thought the brake pedal felt a little funny (not
smooth). I figured that it was probably because
the car sat for longer than usual. By the time I
got to the store, I started hearing a thumping or
clunking sound. Once, when returning home, I
stopped at a red light, and when hit the brake I
thought I felt/heard a sharp knock or pop.
Anyway, the thumping sound is regular, seems to
be coming from the front end, and increases in
frequency as the speed increases. Just for the
heck of it, after stopping at the post office, I
locked the hubs and put it in 4WD. I did one
loop around the parking lot with the Tracker in
4WD. Although it might just be my imagination,
it seemed as though the sound disappeared. Either
that, or it was no longer loud enough for me to
hear it.

I'm guessing that this problem has something to do
with the brakes or one of the hubs. Any thoughts
on what it might be?

-Phil

Re: Thumping noise coming from the front end

just a word of advice DO NOT DRIVE AROUND ON PAVEMENT IN 4WD AS U WILL BIND UP UR DRIVE TRAIN AND CAUSE DAMAGE!!!.
as for the noise check ur brake pads , calipers,and wheel bearings!

Re: Thumping noise coming from the front end

ozbazook,

Thanks for the warning. I knew that 4WD on dry pavement is a "no-no." That's why I only did one loop around the parking lot. I figured that just that little bit probably wouldn't hurt but, then again, I could be wrong.

What is it about pavement that causes damage? This seems quite illogical to me. What about pavement that has a thin coating of ice or snow? If damage occurs, what part of the drive train is most likely to fail?

Re: Thumping noise coming from the front end

When you drive in 4wd the front and rear driveshafts are locked to each other. there is no diff in the
Xfer to allow the drive shafts to run differend speeds in turns. The diffs in the axles take care of the
tires either side of the diff, but do nothing front to rear. tight manuvering can cause damage to the
drive line, by breaking or bending the weakest link. Ujoints? yokes? something will give, if not now,
sooner or later

Re: Thumping noise coming from the front end

I have to disagree with these statements of not driving in 4wd on dry pavement because something may break. Nothing will break, if it does, it was going to break anyways. Driving in 4wd on dry pavement will only wear out components quicker than if you were driving in 2 wheel drive which will eventually result in repairs. There have been many vehicles made with full time 4wd and they were all reliable vehicles if properly maintained. Front end wear was higher and gas mileage was lower but they didn't fall apart and break ujoints every morning as someone pulled out of their driveway. The main thing you will notice is that you will not be able to make a sharp turn as smoothly. If I feel that I need 4wd and the road isn't covered in Snow or Ice that would normally warrant 4wd but I would like it just in case, I run 4wd without hesitation and usually not even noticing it's in 4wd.

One other thing, about the thump, it's hard to say but if you take the time too look at the brake pads, rotors, calipers, tie rods and such the problem will most likely be obvious. Unless of course you hit a cat and it was thumping around inside the tire and when you stopped to lock in the hubs it limped away. ?????? Could be! [img]images/graemlins/puke.gif[/img]

Re: Thumping noise coming from the front end

Hi guys,

Just thought I'd a post an update...

I checked out my Tracker today. Based on the
"wiggle test," I think the wheel bearing on the
front driver's side needs to be replaced. When I
grab the tire, I can wiggle it a little. Not
much, but a little. I tried all four tires, and
the other three hardly budge at all. Considering
that the bearing on the opposite side failed six
months ago, I guess this shouldn't be too
surprising. In fact, I had been planning to have
someone take a look at it as a precaution, but
just hadn't gotten around to it yet.
