More vibration issues.....

I have always wanted to install one,but I saw the cost of a custom DS and cringed.Very expensive.I had never even thought of just having one modified to fit."So obvious I didn't even see it" kind of things.LOL.As I stated before.Upon simply taking off in the car,I could tell it was different.The DS is so light that I easily one handed it into the tranny and up to the differential.Well worth what it cost,which was a lot cheaper than buying a custom DS. wonder how many others here have an aluminum DS already and just never really mentioned it.Heeeeeeey,maybe I'll be a trend setter......whatever.LOL.

Awesome news Vinnie.  Glad you got the vibration out of it.  Mine is driving me crazy and getting the drive shaft balanced will be the first thing I do to it when it comes out of the garage in the spring!

Unbelievable how light weight they are. I thought that they couldn't be all that much less, but wow, a LOT of difference.

Well worth what it cost,which was a lot  cheaper than buying a custom DS.

Picked mine for 20 bucks, and there's a 4 dollar core...ANY shaft will work, so long as I bring one back..I've got one that doesn't have the trans. end yoke. :evilgrin:

Both of the Crown Vic ends go in the trash anyway.You'll need to use the stock ones from your car on the Vic DS with adapter u-joints.Send it to the guys I told you about.They do great work,and do it fast.....wicked fast.For a $4.00 core,I wouldn't worry about it and just call the $4.00 a loss.You're still out for cheap......unless you're going back and have one to take to them anyway.Get it done and install it.

On another note Freek,I have your package in the trunk ready to ship the day the payment arrives.

There is a shop in OKC north of the airport on Meridian that did my DS years ago, I believe it is called Drive Train Specialists.  They built the DS from scratch and it was about $140 total.  I brought them the front yolk and the rear , that was it.  I had to measure the distance from the rear  face on the rear end to the center line of the u-joint of the front yolk.  I fully inserted the yolk into the tranny and then pulled it back approximately 0.75" per their instruction prior to measuring.  I did all of this as I had installed a Tremec TKO and my stock DS was useless after that.

My vibration started here and ended when the motor ate a valve.  I swapped the TKO out for another TKO that was in a buddy's car with no vibrations, completely rebuilt the rear end (bearings, races, gears), swapped wheels out, even went so far as to check how the motor and tranny were sitting between the frame rails, checked and changed the pinion angle multiple times, reclocked the DS, jacked the car up and check the DS for excessive run out, took the DS back to Drive Train and had them check the balance and tolerances (no charge by the way and it was good to go), had the tires balanced on the car...all to no avail.  I even shipped the internals of my TKO to a dealer and he checked all the shafts which were all fine.  Guess I learned how to tear one down...yea me.

My vibration was cyclical in nature and was there if the tranny was in or out of gear at speed.  It was not an rpm based problem.  Like I said, the problem went away when the 306 ate one of the valves off of the AFR heads.  I am just hoping that it is not there when I get it back on the road this summer with the new motor and suspension.  One of the most frustrating things I have ever experienced and I hated driving the car because of it.  I think I was more upset with myself for not knowing how to fix it if truth be told.

I ran across this article by a Ford engineer that I wanted to share.  Granted its a bit of a read and took me a couple times through it to complete understand what this guy was talking about (still not 100% sure I understand him but I think I do).

I'm not sure what you meant by it went away when you ate a valve? Did you mean it didn't run no more? I've had a few motors vibrate the shiznit out of shiznit through the years for different reasons, some I still don't know why. Mostly diesels, Bad enough to vibrate dash boards off there mountings, brake flywheel bolts, brake Trans mount bolts, the list goes on. This is an interesting subject, because it can be hard to find the problem. I do know a few here have this issue. And it may not be a drive shaft.

I called them,and they were a lot higher than Performance Drivetrain.It was cheaper for me to ship the Crown Vic shaft to them,have the work done,and have it shipped back by Performance.

The valve came apart at about 6000rpm between the stem and the head. Basically trashed an expensive 306 but I was able to salvage the AFR heads with some welding on the combustion chamber that dropped the valve. It quit vibrating the hard way so I never really figured it out. I usually watch threads like this to see if someone finds the golden bb that will fix mine.

That is good to know about the cost as I did not know the shop you took it to was around. I may take mine to them and have them check it as a second opinion.

Shipping it a long square box through UPS was only twenty something dollars.Easy stuff.Cheaper than the gas I would've used.

The car is in Lawton so it is about an hour or so from them. My dad makes a trip to OKC at least every other week so I can talk him into dropping it off. Basically free shipping.

Coolness.I used to do my grocery shopping on the Base there in Lawton when I was stationed in Altus back in my old Air Force days.Haven't been back in a long time.I'd like to go there and hit the salvage yards.

Ha ha ha!!! Small world, I started my engineering career living in...you guessed it Altus, OK.  Was a controls engineer at the sheet rock plant in Duke, OK.  Moved to OKC after that and have been in TX for the last five years.  L-Town has some pretty good salvage yards but the one that had the majority of all the T-Bird/Cougar parts closed down and they crushed all the cars.  I was ticked I did not plunder that place earlier but I did not have the $$$ then.  I found http://www.car-part.com about three years ago and have ordered parts off the site and have had great luck.

Will quit high jacking the thread now, sorry.

I've been wanting to hit a couple of new yards,but no time.I'm going to take a week off from work and spend a couple of days hunting for treasure.

Did you lose a spring or did the valve just give out? What model do you  have? As you see I'm interested because I redid my AFR's.

I am pretty sure I have one of the first sets of the AFR 185's.  Ordered them in early 2000, still have the receipt around somewhere.  From what I understand they installed two piece valves that were formed by heating the stem and head and basically shoving them together.  In all honesty the entire valve train sucked but I did not know any better back then.  They now have Manley severe duty valves, Manley titanium keepers and retainers, and Isky 8005-A springs.  The guy that repaired the one head and installed all of this for me also worked on the heads a little bit and cleaned the profiles in the runners and in the bowl areas.  Picked up the peak flow numbers but more importantly the flow under the curve was increased throughout the range of lift.
