It's cake...You simply remove the straps that hold the U-Joints in...Be sure and use NEW STRAPS and NEW BOLTS...You can get them at your local dealer cheap...Four straps per side...eight bolts
Jack up the rear so the wheels can turn. That helps get better access to the bolts. I used a combination wrench with a piece of pipe for leverage. Don't forget the Loctite.
I had to unbolt the lower shock mount to get the shaft out. Others claim it will come out with some wiggling. I wonder if having an ACR matters.
One end wouldn't seat by hand so i use an old strap and eased it in with a couple bolts.
hvy duties over two yrs old and two seasons of racing so im not complaining. over a period of time shit gotta give. way i see it, half shafts are consumable parts just like a clutch is, in time its gonna go.
jimT; depends upon your hp bro; last yr running stock and eventually with bolt-ons i would launch anywhere from 5000-5500 and with psi from 14.5 to 16.
now i launch around 4800-5000 and psi same, im hookin as good as when i use Mickeys. you cannot obviously expect the complete results as a set of slicks and skinnies but for the launch itself; with the right scenario BGFs will hook and stick every bit as good as any set of slicks, period
last night i kinda expected something to happen, as it was 50 degrees, no humidity, track prepped excellent and a cold car. so i added fuel to fire by dropping psi from 15.5 to 14.5 even though it was hooking good already and after a hellacious burnout...wham bam thank you maam, keep my halfshafts you fucking track [img]/images/graemlins/supergrin.gif[/img]
but hey, i was going for my first ten second run [img]/images/graemlins/drive[/img]
all i know is im goin back for theat ten secodn time slip on saturday. i just finished the cats (right one was bad) new plugs (went colder to NGK; indexing them too; what a bitch that is) and the new halfshafts arrive tommmorrow (thnx jonB for manning up when needed)
If you indexed them, did you set them at 9-12 O'Clock. If the plug is positioned at other than that angle the electrode is severely shrouded by the proximity to the side wall. Indexing means different thing in different cars. The viper plug electrode can be hidden in the corner if not turned in the correct direction. There is a lot of debate over this topic, but, on the other hand, few combustion chamber layouts hide the plug as badly as the viper.
It also is not good to add the spacers, as they can change the heat transfer balance of the plug. You should just buy a bunch of plugs and use an indexing tool to measure the the electrode position. It takes about forty plugs to find the right 10.
