Tiburon has slight lean to the right

Hello All

For some time now I have noticed a definite lean to the right (right side
lower than left side) in my 2005 Tiburon GT.

Yesterday I took some measurements (again) and some photos to take to the
dealer.

Measuring from the ground to the top of the wheel arch I get a difference
of slightly more than 1/2 inch measured at both axles. This may not sound
like much but on my level garage floor the difference is quite visible. Not
only that but the rear of the car sits a little lower than the front
although l am not so much concerned about that.

The car only has 13 500 miles or thereabouts and as far as l can tell the
suspension is in good order. I do have a Progress sway bar at the rear but
that did not cause the lean which was there before the sway bar was
replaced.

Any ideas or similar experiences? Any Tib owners want to take some quick
measurements and report back here? Hyundaitech, what do you think?

Best Regards

In most cases, about 1/2 inch from side to side is considered normal.

 

Hello hyundaitech,

h> In most cases, about 1/2 inch from side to side is considered normal.

This is what i was afraid you would say. Here are some numbers I got today
(Track and Angle headers shifted over a bit) --

Unloaded

Left Right Difference Track Angle
Front 25.88 25.50 0.38 58.70 0.005 Measured 10/9/2006, 35 psi in tires
Rear 25.88 25.25 0.63 58.70 0.009 Measured 10/9/2006, 35 psi in tires

Front 25.88 25.50 0.38 58.70 0.005 Measured 10/8/2006, 31 psi in tires
Rear 25.81 25.25 0.56 58.70 0.008 Measured 10/8/2006, 31 psi in tires


Loaded

Left Right Difference Track Angle
Front 25.56 25.19 0.38 58.70 0.005 Measured 10/9/2006, 35 psi in tires
Rear 25.44 25.16 0.28 58.70 0.004 Measured 10/9/2006, 35 psi in tires
So even with almost 200 lb me in the driver's seat, there is still a lean
of more than 1/4" to the right.

Note how the front did not change at all but the back saw a reduction in
lean down to a little over 1/4".

Add to this, the fact that every so often I have moaning sound 2 - 3 times
from the right side (I want to say right rear) on the first right turn after
a long or overnight period parked. At first I thought it was the parking
brake but I doubt it, since the parking brake is not very tightly adjusted
(I easily get 4 clicks before it holds nicely on my sloped driveway). I took
it in to the dealership for a wheel rotation and balancing and asked them
to investigate as the wheels would be off. They saw no problem. Of course
since the car was just driven they could not replicate the noise either.

What do you think that moan could be, and why only after the car sat for
a while? I sounds a bit like a tire would make rubbing on a solid metal structure
-- not a scraping sound but a resonant moan. Since it only happens wehn I
turn right I figured it should be from the front, but the sound almost appears
to come from the RR.

Stop buying the double cheeseburgers for your girlfriend?

 

That is a miniscule amount of difference. I wouldn't worry about it as
long as nothing appears broken in the suspension.

Hello Edwin,

Hahahaha .... I wonder if I should pass your suggestion onto my 'known-to-be-grumpy'
45+ year old wife. ;-)

On paper it does not seem like much, but I can see it, and that is what irritates
me. Thanks for the input though.

If you notice a quarter of an inch, you are looking way to hard for way
too long.

OK, you got my curiosity up. I just went and measured my Sonata, a Ford
and a Lexus. Each one varied 1/4" on one side or the other. I could not
see the difference. This is one of those things I never thought about, but
I'm sure there is a normal tolerance of some sort. Anyone know what it
would be?

 

I'd be a little more interested in the moan than the lean. The GT
suspension bushings tend to wear from the beating of the stiff suspension.
But this doesn't particularly sound like that. Could be a strut, control
arm bushing, sway bar bushing, etc. Next time you take it to the dealer,
take it in during the day with the understanding they'll leave it alone
and check it the next morning.

 

Hello hyundaitech,

Thanks for the reply.

h> I'd be a little more interested in the moan than the lean. The GT

I know what you are saying but I have been fairly gentle with this car and
it only has 13300 miles or thereabouts. No other noises occur.

h> But this doesn't particularly sound like that. Could be a strut,

You are thinking all in the front, right? Since the moaning sounds only when
turning right.

h> Next time you take it to the

Yeah, I know that is the solution, but I am resisting that since I don't
like to be without the car. That said, it does not do it all the time, so
I would take it there and it wouldn't make the sound. At one time I thought
it might be temperature related as it seemed to do it more often in cooler
weather, but then I heard it after work (8 hours sitting in parking garage)
during Houston summer days.

Aha! Note, my car has more like 1/2" before I sat in it.

I would think so also. HyundaiTech said 1/4" was within spec ... don't know
if that is experience or actual. I still think 1/2" is much, although having
said that, today in my office parking garage (where I did not have my spirit
level) the car appeared level. Who knows ...

I'd figure the problem could be front or rear.

Sounds like you've got plenty of warranty left. Mention it on your next
service visit with the expectation they probably won't find anything.
When it finally happens often enough that they'll be able to reproduce it,
then drop it off the day before it will be serviced.

 

This was related to a SantaFe Their was mention of some type of bushing
replacement for the rear shock to correct some type of body moan

Yeah, that's what I was thinking because the sound resonates through the
car's 'frame' which means it could be alter front or rear.

h> Sounds like you've got plenty of warranty left.

Yes I do.

l do mention it whenever I do manage to bring it to the dealer far work. So
far the car has been very good and has not had any work requiring the
specific brand-expertise that a dealership might offer.

I will certainly do that. Thanks for the advice.

This indeed sounds promising. I don't suppose you can remember where you
saw his information ....?

Might even correct body lean. ;-)
