E34 540i / 6 speed Drivetrain issues! Clunk on upshift and take off! Please help!

Hey guys,

I just put a new motor, clutch, motor mounts and im having issues with the new motor..

I get a clunck when i shift witch is odd. The driveline was always solid before the swap as its the 265mm clutch and 210mm diff is should be bullet proof.

On this front: a new guibo and csb has been purchased hoping mouting points on the csb are bad. Idk yet cant see it.. Guibo is ok light crask so what ever..

The Symptoms - during clutch chatter from puck type clutch on engagement and when i shift get a huge CLUNK..

Sometimes its a quick 2-3x., when it let off to shift..

Checked already; motor mounts are solid and new lol, trans mounts are new soon to be solid, all diff bolts and drive shaft bolts on each end are tight.. Rear subframe bushings are ok. Shifter does not move an inch..


Kinda all comes down to the csb or ill have a serious deep founded issue to track!

UPDATE---

Rebuilt driveshaft, new csb and guibo no change.

I next doing my rear subframe mount, then bushings.
After that ill have to try a new CV joint i suspect if ive still failed..





Imput is appreciated..

Pulled my driveshaft to find a stiff U joint!

Lame, cost me about 300$ for new ones installed and rebalanced..

Better keep saving..

Everything is new, and it clunks so bad when i shift its killing me!!!!

I don't think that people are ignoring you. It's just hard to help with something like that that obviously has to have eyes on it. Your theory of the sub frame bushings sounds like a good one. If I recall, you drag race your car don't you (I'm thinking you are the one which such great light skills)? That could certainly cause tremendous strain on the drive train and frame.

Make sure that you don't have a loose or broken axle or diff problem. As I recall also, you changed your diff so you certainly have more knowledge there than I.

Good luck.

Its wierd, it was fine after the races before the swap. It was on jackstands for weeks, if that can effect it..

Ive replaced litterally most of the car, and i cant for the life of me find this.. It seems like it should be obvious.

My next move is call a buddy who is as good as me actually better than me.. Anyways, ill put the front up on jacks so theres room under, set the hand brake. And use running motor and let the clutch load up the drive train without moving, should clunk right in front of his eyes..

So i am ready to shoot myself..

I have spent all day under the car, it is all new,its all tight..

http://www.m5board.com/vbulletin/e34...end-clunk.html

I inspected every thing in those 2 diagrams. There all intact.. Suprisingly good in fact..

It sounds like the diffs jumping into the bottom of my car hard but no marks! None anywhere..

So i jack up the nose of the diff zero play.. Lift the car same for the rear.. WTF

This is my biggest fear, one of those stupid illogical deep seeded issues that can not be fixed.. I fear ive got one.!

Ive replaced everything anyone ever suggested online anywhere minus subframe bushings that look ok..

I tried using a go pro then my starter failed once i got the camera working again.. So SOL.. Again and i get to do a starter motor in the car for no reason now..

FML!

If you're getting a clunking noise they usual locations are:

Subframe bushing
RTAB
Pitman arms aka dog bones
Transmission bushings
guibo (but it's more of a rumble than a clunking)
rear strut mounts
sway bar bushings are shot.

IIRC outside of the noise and possible doglegging of the rear end.
You really cant tell if the sub frame bushings are done unless you remove the bottom plate to inspect them.

Sorry I didn't see this till now. Been in the hospital with acute bronchitis.

It sure feels center of the car, middle to rear.. Something pounding on the bottom of the floor.

Im thinking rear sub frame bushings next, but its just shot gunning now.

When you accerate do you feel a slight adverse jerk and metallic thud. Or is it continuous.
Being it was not present prior. It's something you did or installed incorrectly.

If the noise is continuous it's your flex disc. It's possible that either the bolts are installed wrong.
Or if it was in use prior to the work, your drivetrain is now off balance some how.

I have a revshift aluminum / poly guibo that did the same thing as this.
Turned out the driveshaft was not aligned or balanced correctly and the old rubber guibo was masking the defect.
I will replace the driveshaft later to remedy this. For now the revshift flex disc will sit in the basement till I'm ready.

If it's jerking and making a thud, then it could be the subframe bushings.
For that is what they are notorious for when they go to crap.

Ok..

Car was i believe solid.
New motor
New clutch
Motor mounts
Trans mounts
Guibo
Csb
Rebalanced driveshaft with new u joint
Rebuilt diff

Nothings really left there.. My DS thumped got sent out to be rebuilt put back in zero change

So installed 2-3x wrong? I cant move the diff with a jack its not budging..

What im left with in my mind is the rear CV joint, and subframe mounts..

Subframe mounts make sence but dont feel right somehow.


The noise,

Nothing if u drive soft..

If u dump the clutch, cluck clunck..... ok, vroooooom redline &,

Shift wide open throttle its a bang bang bang.. Then ok

If you get into power from a roll and gun it nothing..its fine


I thinking having tbe front passenger corner on stands for 3 weaks tore weak subframe mount maybe..?

ok so it's not doing it constantly. just through weight transfer...
Subframe bushings. (my $5.00 bet)

Well if that happens to be the case you have some good options.
Go full poly or poly filled.
Go AKG or Powerflex (which I can get... I used to sell them)
Or go OEM replacement which is cool too.

IMO since you drag the car go poly. I have PF Poly subframe bushings. Car feels great.

Replacement is pretty cut and dry. My recommendation is use a subframe bushing removal tool.

First find out if that is the issue. Which will require putting it in the air
or to some extent making that bottom plate available for removal.

Will be doing that today,

I of course will be going to PU or PU filled..
Hopeing they make them 2 piece so they can be cut out and popped in..

Those subframe bushings are shot. Once you pull them, you'll see there's much more to them than meets the eye, as installed....particularly on the upper surface of the bushing.

Don't use power flex.

Stick with the OE bushing and augment them with Bruno's delrin inserts from where ever you can source them.

The other picture is of your car's torque links. They don't control the subframe in any way...they locate the trailing arms laterally and control toe throughout their range of travel.

Na, not a fan of the inserts.. I wanna replace my subframe bushings right, with essentially lifetime units..

I really dont believe this is a clunk tho..

That square diff mount in back looks ok how do i check it!??
I think the subframe is held in so many places i doubt i could make it move by hand.

And jack under it wont show since it will rest on it and lift

Theres is so liitle play in anything that we are baffled!

I fear i may have to take it to a shop once i swap the starter sp i can drive it period..

This whole clunk cituation thats come out of no where is gonna cost me a fortune.!

That crack in the one subframe bushing doesn't look promising. It's supposed to be one solid unit.
It's splitting says it's been seeing some stress or just plain wear due to age and drag
I'd look into replacing them.

I forgot about the inserts. You can use them effectively.
My PFs haven't failed but I do know there are mixed reviews on poly subframe bushings.
So the choice is yours what to put in there.

The other is a rear pitman arm or Dog bone. Yes it's shot.

Anyone ever have a cv lock up and throw the driveshaft for a loop only under sudden full load scenario's???.. IE launches and hard shifts..

Thats what it feels like, but perfect otherwise, wtf

If my subframe is not moving, my diff is not moving. And The motor and trans are not moving.. Csb and guibo is new plus the shaft was balanced and new U Joint..


Can it only be the CV?

Is there any other possibility? Idk if i replace this or go to a shop next chance i get?

Any updates on this? A fix?

Thank you.

UPDATE...

I just found your build thread which detailed this, as well. For those searching for a solution to a problem with similar symptoms, his build thread is here - http://www.bimmerfest.com/forums/sho...=723568&page=4. The resolution is near post 100. It seems new subframe bushings were the answer.

Side note, I also have this issue and have replaced my subframe bushings with no improvement.

Anyone who drag races an E34 deserves the car troubles that follow, these cars are not race cars in any way.

Wow, those who can't criticise...

FYI, if you could read you would know nothing bad ever came from drag racing..

This started after the swap... So go somewhere else lil hater...

They may look fine but your subframe bushings are gone and your trailing bushings need to be swapped out. Ive personally had this issue with my e28 and my brothers e39 540it/6 does the same thing right now. Any bit of tearing on the bushings is a good sign it needs to be replaced. OEM is the way to go. Bavauto sells a full suspension rebuild kit for $450. It comes with balljoints, bushings with control arms and I believe tie-rods all for the front and also new bushings for the rear.

There PU from powerflex, i recommened everyone weather its a DD or a track car use them.

They are much easier to install and last forever... There really is no drawbacks.. F using OEM rear SFB's!
