well it looks like part of my vibration problem is due to the fact that the guy that welded my brackets on the 8.8 welded them just a couple of degrees low.my tera upper arms are allready showing threads and the coils are bowed just slightly ,but the pinion needs to go up just a couple more degrees. so do i just come up with some longer arms? or since the 8.8's seem to have a problem rotating there tubes anyway , could i just heat the pig up and rotate the tubes to where i want them? and then just weld the tubes in place? any other suggestions? thanks


joe

what's up joe?

I rotated mine! Well, one of them anyway. Bent it too. There is supposedly a .003" interference fir between the tube and the housing and it it plug welded. If you twist a tube, it renders your housing no good from what I have been told. I am going to get another axle and part mine out.

My F8.8 tubes are welded to the housing & it seems to have worked fine for me so far.

Nope its not that easy. For one they are pressed in and also they have welds already. So you can't just heat it up and rotate it. It will be easier and cheaper to get longer upper arms. Brimy311 on MJ can probably help you out with that cheap and he is probably the closet fabricator to you.


Alright another question I want to ask first is how many threads are actually engaged? How much that is showing doesn't really matter, how much engagd does thoguh. You want at least 1x the diameter of the material.

well i think the longer arms are the way to go .i'm just getting desperate to stop the vibrations. but i have been moving the pinion in 2degree incriments and still can't figure it out:confused: i just sent koz an email to inquire about prices for the new arms so i'll wait for him to reply before trying brimy311. thanks

Did you always have the vibrations since the axle swap? Also do you have and SYE?



Also like I said check how many threads are engaged, becasue they might actually be long enough. I know on my front arms from RE you can extend quite a ways out and it almost looks scary how many threads are showing and yet its still like 1-1.5 times the diameter still.

joe---I would just cut the uppers in the middle and sleeve them...that way, the arms longer and stronger. Do you already have a SYE with a CV joint?

so this has worked for you for how long? any special prep before/ during welding(nickel rod/wire)? the reason i ask is because the cast center section and axle tubes have different flex characteristics and usually the weld just cracks free of the center section from what others have said. thanks for any info you might have.:beer:

I welded my 8.8 tubes last fall, it's worked fine, and I have hellatious axle-wrap and the wrap bar is welded to a tube.

As far as prep... Yeah, prep... I cleaned the weld area! Other than that I just decided to blast it on with a flux core wire feed, at 130 amps DC I got good penetration and it didn't crack.
