what happened?... pulling away from a red light. I hear a pop.... then the engine revs freely... not connected to wheels.... what could have happend... looking at the car at the house at first then will be sending it to the porsche dealer.. thankfully my father works at the dealer so it shouldnt be too exspensive... no fluids on the ground where it happend, oil level is fine, engine still revs normal... tramsisson still shifts... no bolts on the ground.. what could have happened????

Hopefully no more than a cv joint or axle!

hopefully, honestly i smiled as it died because i knew... at least it wasnt the ims haha, no engine light or anything. Just no connection the wheels which is very odd.

i have been hearing an odd noise when leaving stops.. like a metally squeek sorta thing, just assumed the suspension was warming up as it would always happen early after starting to drive... really hope it is nothing over 1.5k because that is about my budget for now. Yet again Thank God the engine is good.

I'd be willing to bet that the bolts on one of the half-axles sheared off at the trans or broke at the joint ;)

Good news? The engine is still running and new axles wont break the bank.

would i exspect anything to dangle benath the car? i realize how lucky i am that its a fairly normal car non porsche non aos non ims non rms sorta issue haha

Possibly, but not necessarily. If it is a half axle issue, it just depends on how and where it broke. Could be trans or clutch related, too...but lets hope not ;)

I've seen several cases where the axle-to-trans bolts fall out or break, usually due to not being replaced and torqued correctly after being removed.

+1 on this. Should be able to push the car a few feet & hear the axle jumping around to verify. If the bolts came loose get new bolts (make sure you get the right length)
clean everything very well & use blue loctite on the bolt threads then torque to spec.

My vote is for clutch disc

how much is a new tip tranny? if its the worst case scenario.

A rebuilt tiptronic is in the $3-4K range but I'd bet half that that it is the axles. Not a huge deal.

Expect to pay around a couple grand for a replacement tip...

yeah doubting its a tip.. read some old threads about peoples cv joints going out... sounds very similar. fingers crossed haha. :ah:

Crossing for ya! ;)

okay was moving the car around in the garage to allow room for another car... put the car in neutral and turned it on for power steer... as we moved the car it went clunk clunk clunk when it rolled in neautral... once where it needed to be i put the car in park... a loud sound like an air compresser commenced.. i quickly cut off the engine... i then pulled up the parking break fairly lightly, as much as i usually would.. and the car procedded to roll.... after moving the car back. i parked it again pulled the emergency break up way high and it stayed.... placed things beaneath the wheels to be safe, now it sits till we can look at the car this weekend, any help diagnosing the problem, why would it make that sound in park, is my trans mish dead, would anything cause the parking break to not be a grippy?

Parking brake cable attaches directly to hub then to those inner shoes. can't imagine why an axle would affect the P brakes. Clunk clunk clunk may indeed be separated axle flopping around as it rolls or CV bouncing around.

Best O luck and wishes, bro!

good luck
 

let us know what happens doesnt sound like tranny

Bummer man!

Story would have been much better if this had happened behind a School Bus with all the kids 'ooooing' and 'ahhhhing' :P

Hopefully nothing serious

Haha, I thought of that myself.... "We'll it's a damn good thing it didn't happen yesterday behind that school bus."

So me and my father are likely going to fix this ourselves, he is ver experienced but not with Porsches, as for me it will be one of my first larger services aside from helping out remotely with a mustang engine swap. Would y'all suggest to go to the dealer instead?

Come on, man!! Diagnose this already and stop keeping us in suspense!! It's like some new tV show with a serious cliffhanger episode!

Web cam? Live updates?

If its the separated axle its a DIY job, although if bolts sheared, getting them out is a pain. No Porsche specialist required for that.

Honestly in my opinion most everything can be done DIY if you have the right tools, patience and will read the manual and will always be cheaper than the dealer.

And there's the rewarding feeling of knowing you did it right, 100%, and know exactly what was done and now own tools for your next job. Interweb points for taking this on!!

the car will sit untill this weekend, only then will we know haha. When the water pump went out on the PO aperantly she kept driving and blew a head gasket. that was about 5k miles ago (they basically did that service then sold the car to get the money back out of the service as they had already bought an 07 box and the old 99 was just a weekender) The place where they had this major service at seems a little bit dodgey, i wish i could remember what this place is called, all i know is they service ferrari and porsche in charolette. But point is i am assuming the bolts to the cv were not tourque properly when replaced after the major service, causing them to likely sheer while pulling away from the red light. Will make sure to take pics of the damage and such this weekend :cheers:

Dealer will do it quick, not cheap but it will be done correctly and coming with warranty etc. Always good to have the opportunity to get a trained P mech under the car also... if you don't know any good indy in your area.

DIY if you like to "fix" greasy stuff mounted with big bolts - I hate it!

Sorry to hear about the break, cheer up :cheers:

...and don't forget to buy a gif for your dad btw

Dodgy indeed. Was a leakdown and compression test done before it was sold?
I hear blown head gaskets are nearly impossible with these cars.

That's true. Good idea to have the cooling system pressure tested.

yes, we actually were not told of the major service when we bought the car, we found it in the records the night after. We were simply told the water pump had went out already. But yes compression test was done, the place also filled the engine with 0W-40 going into summer in the south...... topped off the oil with a matching weight when we bought the can and plan to change to 10W-40 going into spring.

Jake, you could crawl under the back of your car and see if there's any fluids leaking. Then twist on the half shafts and see if they're secure at each end. Use a flashlight and look for carnage around the rubber cv boot covers and suspension. We gotta' narrow this down and get you back on the road!My bet is a snapped cv joint but I can't explain the compressed air sounds...

my bet with the air compresser sound was when putting the car in park. the tranny is trying to activate something back their, and if nothing is connected that would explain a strange sound when shifting into park. think i will go take a quick look, cars in an akward position so im limited though

Still zero leaks.. Oil level still high... I can only get to the rear right and I can hardly see the cv... Everything is still holding firm though nothing lose here on the back right at least

took a beauty shot while cramed between my car and the back of the garage... buttt... i made it to the left side so here are comparison shots http://986forum.com/forums/uploads01...1391033616.jpg

that was right side.... this is left side....
http://986forum.com/forums/uploads01...1391033658.jpg
that is the inner mount of left side.... a little bit off eh.... :cheers: #diagnosed!

now the question is, do i replace both?

http://986forum.com/forums/uploads01...1391034386.jpg

better left side shot

Is the left inner joint broken? Can you push it up and down?

Left is sagging and resting on whatever that may be it is resting on

Drivers side to trans bolts came loose. I'd replace all those bolts.

Isn't there a stub axle that the inner cv joint attaches too? Did it shear?
