For those of you that have the 04 TL and have experienced engine vibration or drone, has installing this "damper" helped or resolved these issues? Do the model years 05 and above have these same issues? My dealer is just now willing to install this on my 04 TL which has 58k miles (after I showed them a copy of the TSB for this problem). I complained early on about this in 2004 and was told this was normal. I simply learned to live with this. Your thoughts are appreciated. Thanks.

 

I had it installed, and it *is* better, albeit not gone.

 

i too had it installed and i noticed a significant difference at around 50mph. however, at 70mph, i feel a slight drone after the damper install that was not there before. not nearly as bad as the 50mph drone though. go figure

 

has anyone done the damper install? According to the TSB info, it looks like a simple DIY... remove a few bolts, install the damper and rebolt. The TSB shows part# 50207-SEP-305, but i didn't have any luck finding it on acuraoemparts.com.

Has anyone had a dealer take of this when being out of warranty?

 

It's $88 at my dealer but is on backorder here. I will install this myself, seems simple enough. I wish I knew about this sooner.

 

can someone post the TSB or a link? is this only for higher speed vibration or the idle vibration too?

Is $88 the best online price for the Damper Kit or is this directly from your dealer parts dept?

It's for the higher speed vibration, however, I seem to get the same vibration at around 1500RPMS, whether I'm in park or 5th gear. It is much worse when in 5th gear/55mph. I need to check my engine mounts as well.

 

The $88 is what my dealer quoted me for the part.

 

The dampener reduced the drone/vibration, it did not get rid of it. I just avoid 1500 rpm now.

 

That's not the easiest thing in the world to do...

 

I may have another problem an addition to the 1500rpm vibration...

I have done some more testing and I have a fairly bad rumble that occurs between 50-60mph -- It can be felt throughout the entire car. I just had the tires/wheels balanced and had them inspected to ensure they are all straight. The rumble is still there even when I drop it in "N" during the same speeds. Being that it's present when coasting in "N", wouldn't this rule out the engine mounts and tranny?

 

i would think so, i'd think this narrows it down to the transmission output shaft, axles, wheels, wheel bearings, and tires.

one thing to try is to drop it to N while at the speed, and rev the motor a few times, see if it changes at all.

 

I'll give that a try and see what happens... If the tranny is on it's way out, would the output shaft be affected?

number 21??? or i could be wrong

 

That appears to be the correct part, but the price and part # do not match the TSB.

 

yea because the parts im pointing to are for the 08 model and the parts we're looking for are 04, i was going nuts trying to find it because i knew i saw it somewhere.
i have the subframe from the 07 model because i had a problem with it and they covered it under warranty...i know the damper isnt there.... im thinking if i should put it in or ask the tech to do it because a few $$ isnt anything and Im on the 6mt and still get a vibration, especially at 60mph.....i check all the rims to see if they are straight and balanced and they are.
the only other thing i can think of is the damper and 2 mounts are broken but im waiting on the new motor mounts made by innovative to drop before i bring it to acura.

 

I assume we would need the base piece (#22) as well? Makes sense to me. Basically $70 total for #21,22, and the two Bolts.

 

i doubt its the output shaft, its just not something i hear going bad on most cars. but i did mention it because it is one of the parts that rotates with the wheels, no matter if you are in gear or not.

i would check the other parts i listed, especially bearings.

have you rotated the tires front to back to see if the vibration/rumble changes or moves around?

i would tend to rule out motor mounts, because those usually vibrate in time with a certain rpm range (from engine vibration) and not vehicle speed.

 

the motor has abnormal startup and shaking when in idle when the mounts are busted..... even when driving.... u can tell the difference right away if its a rim or axle or motor mounts especially if ur the daily driver for this car and have experience with the fixes on it.

 

what do you mean by abnormal startup? The engine does vibrate quite a bit when cold and when it's in park between 1200-1700 RPMS. It's smooth when idling around 800RPMS (once it's warmed up), but if I'm on the throttle(while in Park) and hold it at 1200RPM's -17, there's a vibration throughout the cabin. I'll inspect the bearings and motor mounts.

 

motor mounts would cause rpm related vibes. you have been complaining about speed related vibes, so when you put the motor in N, and are coasting, and the problem is still there, that rules out the mounts for causing that issue.

 

Are there any updates on this issue/fix? I have an 04 6sp, which has both speed and rpm triggered vibrations. I recently purchased is with 68k and can only assume that the mounts and other peices are all original. I see the most vibration briefly when the engine hits 1200rpm, whether in gear or neutral. I would like to give the dampener a try but do not want to create a bigger issue. What advice can be given to help eliminate as many culprits as possible before adding peices?

Thanks

 

mc im on the long pain in the ass waiting list for the new motor mounts developed...im more than sure anyone whos got the 6speed will need them..... im dropping the car off as soon as i get them at acura to have the damper done as well as a million other things.... ill keep u posted when its done

 

I finally just got around to installing this today. It is very easy to install but if you are going to do this yourself make sure you have a torque wrench since the included bracket is aluminum.

 

I've got a 5AT and I'm getting shaking between 30-40, mostly when accelerating slowly and alot more when going uphill. The vibrations stop when it shifts to 4th but it's always at the end of 3rd right before shifting up. Would this be caused/fixed by the damper? Any other tests I can do to determine the problem?

 

Sounds like the transmission is going. PM 01tl4tl and he can help you out to determine weather it is the transmission. I think its the torque converter failing...

 

I had this vibration dampener installed on my '04 TL earlier in the week. As others mentioned, it won't completely fix the problem; but, it is noticeably better now.

 

did anyone buy 50420-SEP-A01 ? Is this the same as the one being issued with the 04 TSB? My dealer insists that my vibration is due to a bent rim. Took it to my tire shop to get it checked, they said they were all ok. Who's lying??

I'd rather just buy the part and install it myself...

 

Was this damper designed only to be applied to the TL with the 5sp A/T? Reason why I ask is because I was considering picking it up to see if it helped with vibrations but noticed in the TSB that is said it was for A/T cars.

Has anyone installed this damper on a 6sp?

 

I don't think there is a place for it to fit on, and as well the 6spd shouldn't need it as it doesn't suffer from that same drone/vibration that the 5AT's caused at 1500 RPMS.

 

I have never experienced any of this with my '04 manual TL. I didn't even know of such a problem or concern.

 

I did this TSB on my 05 and it has helped quite a bit. The dron and vibration is not 100% gone but so much better now.

 

Did you do it or have it done by the dealer? If it was a DIY, was it easy? Also, do you have the part # that was installed? Is it the same # as what's listed above?

 

I do admit that there is a drone at lower RPM's (perhaps around 1700 to 2000) when the engine is still cold. But once it warms up, this disappears. Same thing occurred with my '02 Altima SE to a degree and my '88 Mustang LX 302CID.
