yes please response.
I have tried your test (neutral on hwy at 80 km/hr with gas) with same results as you... the vibration goes away.
I was going to go to the mechanic again BUT yesterday a light post jumped out of nowere infront of my TL when my wife was driving it and scratched it and bang it slightly on the front bumper and side fender. rrrrrrr
now i need the mula to repair it.

Got my can back from the 2nd shop, (the one that said that I needed hub rings). Still have heavy vibrations! This is getting under my skin!!! Do you guys think if I took it to the dealership they'll know what the problem is? I think thats my only option since no independent shops know whats wrong.

What do your halfshaft (driveshafts) look like, are the cv rubber covers intact or broken, does anything look or feel loose when you grab it and shake it, look beyond the wheels to what would really shake the car.

njzprettyboy

Why arent you guys getting your axle bearings checked? My friend had pretty much the same exact symptoms as most of you...its all back to normal now

SwampGas

That's on the list.

- Control arm
- CV joint (or knuckle or something)
- Axle bearing
- Motor mount

Can you check the axle bearings yourself? And does checking out the CV joint rubber or control arm require taking the wheel off? If it's something simple like checking the motor mounts, I can't justify an $85/hr labor charge if I can see it myself.

Clean AC

Everything looked good, but I did just do a quick look. I'm going to check everything that has to do with the suspension, as well as taking out my coilovers and struts and checking every part!

Clean AC

The shop checked them and said that the bearings were fine.

your rim can be bent and be at "0" balance at the same time. and you will still have wobble.

Clean AC

rims are ok, were already checked

DIRTYJOHN

i have the same problem b4.. What i did was change the spindle.. the best way to check is.. jack your car up take the front wheel off.. and shake the spindle.. It might be really lose... OR BROKEN. O and there is a bar.. I dont know what it is call.. It is connected to the lower control arm into the short frame.. well i change that out too... I WASTED MONEY BUYING THAT.. BECUASE MINE WAS JUST LOSE.. Im pretty sure that is your problem.. That little bar is moving back and forth... causing the car to shake. ITs a 11/16 bolt i think LMK something..

SwampGas

Had like 10 minutes with nothing to do, so I jacked up the driver's side (since that's where I feel the vibration coming from) and wiggled everything. Nothing moved except for a tiny bit of play in the rod that spins the wheel.

The engine vibration is getting worse...you can REALLY feel gear changes now, especially when clunking into reverse or drive. I think this is related to the motor mounts.

One of these days I'll have some free time to at least get the side mount changed.

Clean AC

I found out the problem with my car!!! Thanks to one of our AZ members for helping me out (Soyboy26). We took my car up to the Acura Dealership to get it checked out. It turns out to be my Axle's. The innerjoints have had alot of stress due to altered suspension and different weight on wheels. Thanks Soyboy26 for the help! CLN AC

fsttyms1

See i didnt think it was the rear. Thats why i questioned it. Good that you found the problem.

SSMTL01

Which part of the axles specifically? Do you know how much they are to replace and how hard it is to DIY?

Clean AC

I believe it was the innerjoints, but I know the whole shaft needed to be replaced. I got mines from on of Soyboy26's supplier. PM him and he can work something out for you.

SSMTL01

So have you already installed them? Did the vibration go away completely?

Clean AC

no, not yet. Me and Soyboy26 are installing it today. I'll get back on you if that took away the vibration.

Clean AC

Both axles were installed today and yes that was the problem to the heavy vibrations @ 40 MPH! Mad props to Soyboy26!!! Feels like a new car now!!!

fsttyms1

Cool!

SSMTL01

awesome! post up some details man- ease of install, time needed, part costs, etc

fsttyms1

the hardest part of this install is removing the halfshaft nut. The rest is easy.

carlos gonzales

so what is the actual name for the part that needs to be replaced??.... is it half shaft axles for both left and right front tires?

SwampGas

You're talking about #17?

fsttyms1

No. If you take your wheel off and you see the large nut in the center of your rotor. Thats what im talking about
The large nut on the very right at teh end of the axle

SwampGas

This looks to be a little over my head...

Does that shaft assembly come like that or do you piece it together? Also, if you remove that nut in the middle of the rotor does that disconnect it from the hub? Is there another nut holding the other end to the engine or does it just pop out?

Is there a clear way to identify that this is the problem other than leaving my car at acura? I had the wheel off the other day and wiggled everything...axle wiggled a little bit but it felt like the normal play like how you can move the wheel a little bit back and forth in park.

SSMTL01

Acura told me my axles were fine and it ws my rims I wouldn't depend on them completely.

Does anybody know if there is DIY around anywhere on changing the axles?

fsttyms1

Baisically the halfshaft comes out in 1 piece. You FIRST remove the center nut. That is the hardest part, as it can be really tough to get off. I have broken a 24" 1/2" breaker bar having to use a 4' pipe on it to get it off. Once loose, then you remove the shock fork and separate the lower ball joint. lift the ball joint up and out of the pocket pushing that end of the halfshaft out of the knuckle. Once out of that place knuckle back in place. Now dont just yank on the halfshaft. Get a prybar behind where it meets the trans and pop it out while Gently pulling on it. It will just pop out. Thats it.

The passenger side is the same, except it has a intermediate shaft to make them equal lenght. The halfshaft just pops out of the end of the intermediate shaft where the bracket is bolted to the motor. You can pull on that shaft as there isnt a joint to separate by pulling

fsttyms1

Try rotating your tires to see if it goes away, or Im guessing your running aftermarket rims, throw your stockers on and see if it goes away first.

SwampGas

Guy I know at another dealership is going to give me a hand changing the motor mounts. Since he has a lift, I'll rotate the tires and while the tires are off, I'll look at the axle again.

Excitement happens on thursday...hopefully this stupid wobbling vibration will be gone.

SSMTL01

already put the stockers on- problem didnt go away. Thanks for the write up! How much would a shop charge to change them out?

SwampGas

Replacing the front/side motor mounts didn't fix the vibration, but it's night and day for gear changes and shifting from reverse to drive and vice versa.

SwampGas

Appointment at acura on monday. I bet they're going to blame it on my hideously warped rotors putting undue stress on the bearings or axles.

demolition_x

I have this same exact problem. it happened about 3 months after i lowered my car. f igured it was camber reated and just shrugged it off. i raised my car since its still under warentee and took it back to acura. they said every thing looks perfect its your tires. hard to believe told them to switch tires with anothet tl-s to make sure. they assured me it was my tires. this was back in november. ffwd to a weekago. i put my snow tires and stock rims back on they have maybe 10k miles on them if that. same problem. so im gonna take the car back to them and give them a print out of this. rotating my tires did nothing. the problem only happens under load and as soon as the gas is let up there is no problems.

im pissed cause i had my tire guy tell me that it was cv joints and told acura this and they still said it wasn't.

i know the new shafts and joints are like 100 bucks a peice from advanced auto so its cheap to do if you have some tools and a few beers

now i do not know if this has to do with my car being lowered, which i can't understand. it should put less stress on the joints because they are not at such high angles.

well i hope they can gfix this problem b/c if they don't im gonna go to a different acura dealership

SwampGas

I haven't done any custom work to the car.

If I sit in the waiting room for over an hour and all I get is "rotate your tires" after rotating them twice already, I'm going to be upset

SSMTL01

I sat there for 2 hours and thats what i got

SwampGas

I'll coordinate it with work so that they call about an emergency...maybe they'll loan me an '07 TL for an "extended test drive" to get to work.

01tl4tl

Any alteration to the ride height is going to change the steering geometry, suspension loading, weight transfer and loading on the cv/axle shafts/bearings

Expect more things to need repair if your alter your car from stock height.
Thats just life in the fast lane

jreidstl

hey guys, i just found this thread, i'm having the same issues with my tl as well. I'm having a bad vibration on the driver side. The best way to describe it is like a warped rotor, but i know thats not it. The rotors were turned a few months ago, and when braking, the steering wheel doesnt go all haywire like it did before the rotors got turned. When I accelerate, 1. the car pulls, not really bad, but it does to the driver side, 2. it almost feels like a flat spot in the tire but i just had my front tires replaced so it shouldnt be those, and 3. the whole car itself shakes from side to side. Did anyone else have these same problems before? I was told my front tires need to be balanced, but from what i understand, the balancing issuse should be more so of an issue at higher speeds (which it is lol) damn, this is gettin on my nerves

SwampGas

This is not a balance issue for me because it happens only during acceleration. If it were balance, it would happen all the time.
