you have a buddy with a Z? swap driveshafts, see if problem persists... will just cost ya some time and beer

 

new city, no friends

plenty of beer though

 

post up in regional section, i bet someone would help ya.... and you get to meet new people at same time

 

i have, something about nashville that is exclusive.
I'm not a big meet kinda guy but i'll probably look for a facebook group.
Hard to let someone swap a driveshaft without knowing them for awhile

 

i am really at a loss, I do not want to drop the trans to look at the clutch or the pumpkin...this sucks. Why can none of these shops help...

 

Near Nashville? Doug Crawford at Crawfords Z Car Garage:

One of the best.

 

Is the wobble EXACTLY the same as it has ever been??
You NEED to have the driveshaft MEASURED...... ( by someone who KNOWS how to use that tool )...
Can you recap everything that has been done or experimented with ?

 

Right close to nashville. 15 mins or so away

I'd be curious to know why you think he is the best?
He was the second shop that had it and suggested I go get a $200 tire balance.

Recap of everything done
- Stock set of wheels and tires tried
- Tires mounted and balanced x4 (wheels tested and were true)
- drive shaft unbolted to check u joints
- Diff bushing replaced
- rear shocks replaced
- Driver side axle replaced
- Car was put on a dyno and while on the dyno it shook like it was on the road. (hence all the rear end work)

I reading other threads with similar shakes and people are saying replacing the compression rod bushing fixed it. It just doesn't make sense on my car as the bushings look good and the dyno run makes me think its in the rear.

I'd like to add that every shop except the very first has had the car for at least 24 hours to diagnose a problem.

 

Burn it already. This is getting ridiculous.

 

Just checking the U joints visually, is not enough... it must be measured. Failing that, it's just guess work, and FRUSTRATION. Take it to Nissan and let them have a look at it...
Things turning at a high rotational speed only need to be a gram or a thou or 2 to do this.

Has the car ALWAYS done this, since you owned it?

 

"I'd be curious to know why you think he is the best?"
Please don't misquote. Wrote "One of the best".

Doug Crawford has specialized in Z's for 35 years.
Might do you good to talk to him & let him know what's been done. He's very accessible.

Other options might be to pick up a $100 driveshaft & a four bolt DIY or make an appointment for diagnostics with Dynosty in Louisville.

Sympathize with your problem & appreciate your goal of keeping your Z in good mechanical form. Good luck!

 

I think this answer the best.
I live at 123 main st and will roast marshmallows with you while it burns

Has not always done this or i would've burnt it by now.
4 months and counting.


While i don't doubt he's worked on them for that long. He could not fix my problem. He was the second shop I took it to.
He also had a problem taking it up to 80 mph (he wouldn't do it)
He told me what I would've expected nissan to tell me...live with it.

I guess i will leave it with a shop over thanksgiving and have them pull the driveshaft and get it checked. maybe i'll just part it out and call it a day...semi serious

 

If you ever need a doctor for a health problem, please let someone else choose one for you.

 

anyone else have any ideas?

 

Has this been rectified? I have the same issue with my 07 z. I have full camber/toe battle version arms in the rear with new energy diff bushings. Just had an alignment and wheel balancing done. I have the "bouncing up and down" feeling after 20-35ish and the vibrations through the driveline/shifted/seat around 70-85ish. It vibrates even when clutch is pushed in(vibrations increase while under load obviously). Any help is great, thanks!

 

I'm in the same boat now too, and have been referring back to this thread in hopes to find a solution to my issue...replaced 2 sets of tires, axles, had run out tests done on rotors, hubs, drive shaft. Replaced differential bushings, trans bushing, and still nothing has been fixed. If anyone here, yes I know how old this post is, has any other advice, I would greatly appreciate it.
