So yesterday I installed some bc racing br type coils on my tl. After some trial and error I got it to the height I wanted and was on my way. I noticed some wobble on the first drive during acceleration. When I got back I made sure everything was tight and secure which it was. So then I figured maybe something a well needed alignment can cure. But after my alignment today the issue still stands.

Any others experience this? Any info is appreciated

A lot of variables to your problem.
This issue start after the new coils installed?
Did you tell the alignment shop before hand with this issue?
What did they say?
And how bad is the wobble? Just some ?

Yes issue started after install and I did mention it to the alignment shop. What they told me is that they would check everything over and assume the alignment would correct it. As far as the wobble goes, it gets worse depending on how much throttle I give. Once at cruising speed it's fine but accelerating to that speed is the issue.

Your tire could be out of balance?

I didn't think about that but they are just the stock wheels. Lowering doesn't change that does it?

yoks032rs

The tires/tire could have been out of balance at stock height and the softer shocks
could have disguise the wobble. I don't know. It might be something simple as balancing.
Or it might be the process of illumination.

True, ill check into that

I would guess that your axles do not really like the new geometry they are operating under.

Could be your axles, they can start vibrating when you lower the car. Since you say it happens when you accelerate, there is a good chance it's your axle(s). How low did you go?

allwhit3g

Lets just say I'm part of the "moar low" crowd. Does this mean I have to raise her? I've seen plenty of static tl's sitting on the ground, what's the best way to go about this without going back up.

allwhit3g

iTrader: (2)

would a front camber kit correct this?

allwhit3g

iTrader: (2)

sorry for the bad iPhone pic but its all i got for now, and I'm not this low. I went up 1.25 inches for fender clearance, but its pretty damn close

I think you'll have to replace your axles for it to go away completely. If you raise it up it will be less noticeable. If you have an automatic then you should get Raxles, many people say they are really good and OEM ones are ridiculously expensive. OEM 6spd ones are way cheaper for some reason.

I've just learned to live with the slight vibration at around 20mph after I raised my car up a little when it was really bad.

allwhit3g

iTrader: (2)

well good to hear the 6mt are cheaper. So getting a camber kit and new axles is probably the best way to go? I'm guessing the axles are now bent?

AcuraCake

iTrader: (3)

I don't know if getting a front camber kit will help, but it wouldn't hurt, especially if you're pretty low. It's just that your axles are now at a different angle than before and they are not used to that angle which causes the shaking during acceleration.

allwhit3g

iTrader: (2)

ok so just to be sure; new axles put into the current angle, given the lowered car, will be just fine?

This is what I'm not 100% sure of and that's why I didn't replace my axles. I started a thread a while ago and someone said that they should last on a lowered car. Here's the thread: https://acurazine.com/forums/3g-tl-problems-fixes-114/new-axles-after-lowering-892104/

allwhit3g

iTrader: (2)

got it, thanks for that. I'll stop by Acura and see what they say. I spoke to a mechanic friend earlier and he said a camber kit should correct it but ill see what an Acura tech has to say about it. How long did you drive around with the vibration?

pohljm

do you have excessive camber you need to correct? dont think the camber kit will help the axle vibration, thats just a worn cv joint trying to operate at a new geometry.

allwhit3g

iTrader: (2)

so then replace the axles and it will go away?

So did you replace axles? Got the same wobble after lowering the car.

leasureryan

I put 2 new axles in same time I slammed my car, did brake/rotors, upper arms, rear camber kit. Figured it should be good. Still shakes. I just don't think that the axles were designed to be used at the angles they are at when slammed. Can't expect OEM ride out of a modified car. Also, check front motor mount

Yeah I've had this problem too ever since I slammed my car on Tein SS. I replaced my passenger side axle with a new OEM one, the wobbling went away for a bit and then came back. It's most noticable when I'm accelerating in 3rd or 4th.

I think I'm going to try changing the driver's side axle and intermediate shaft next.

TLOHTL

I too have same issue. I just raised the TL 2"s all around a few weeks ago for the great Canadian winter lol.... And the car does NOT vibrate at all. It drives MUCH better and seems like it accelerates better too. But every time I lower it..... It wobbles sooooo much on take off.

It's 2005 6spd Brembo navi TL

- it's on type-s rims with 245/40/17 tires and it's lowered right onto the tire. Less than1 finger gap all around.

I have :

Re-balanced tires ( no issues with the balance )
Front & rear camber kit
No camber issues on tires
Alignment

Honestly the 04-08 TL is a MONSTER truck from the factory.
When you lower it 2+"s I just think it throws the angle off on the axels.

I would really love a fix to this issue....but I would rather drive my tl with a wobbly steering wheel on take off than drive it in MONSTER truck mode lol ....


If anyone has a fix let me know....

when you are that low, the position of the hub requires the cv joint to be constantly at an angle. theres nothing you can do about the vibration that comes with that. new axles will only last longer but its still going to be sitting in an awkward position

azeezp13

So what you're saying is, every single slammed TL on this board drives like shit?

leasureryan

yes lol

nttstt444

iTrader: (1)

I bet the vast majority of outright slammed tl's handle and ride like Shit. Its such a dramatic change in geometry in the front end. The car just isn't designed to sit that low.

azeezp13

iTrader: (4)

Hmm.. no that's not right. A stiff ride is one thing, but even a slammed car shouldn't have this 'wobble' a lot of members are experiencing. I have a friend with a TSX on chopped stock springs on Koni Yellows and it drives much better.

Like I said, when I changed the passenger's side driveshaft I did see an immediate improvement, but after a while I got the wobble/shaking back. I will change the driver's side and intermediate shaft next, I'm hoping it will solve this damn annoying wobble.

nttstt444

iTrader: (1)

It got better because you replaced an already worn axle with a new one. I'm sure replacing the driver axle and int shaft will make it better. But the wobble will come back eventually as the cv joints wear at an accelerated rate.

So what is the ideal drop for our tl without the wobble or straining/stressing too much the axles?

jkballin

Had the same issue. I installed a new passenger side axel and it was immediately better. It's been a few months now and the wobble is back.

Mine shakes after coilover install. Oh well who cares. The car look cool now, that's all that matters. Just learn to live with it or raise your car

FamilyGuy

Anyone know?

nttstt444

iTrader: (1)

Yeah, who cares If the car drives like shit, as long as the subframe is on the ground its all good!

FamilyGuy

I care

nttstt444

iTrader: (1)

^I guess I forgot the red text...

FamilyGuy

lol

FamilyGuy

So what are we looking at...2" drop max before the axles start to wobble?
