ive been using az axels for a long time changed them with other az axels too never any problems had neuspeed springs now ground controls i would guess your problem is elesewhere if youve tried a couple sets and still no good maybe somethings bent since you said the cars been rebuilt.... midshaft?

 

I rebuilt it, nothing is bent. I welded in a new core support and frame section. Also replaced all suspension parts including sub frame and steering rack. I have put probably 500 miles on the car since I did the repairs and seen 120mph + with no problems until this axle BS.

 

Probably not it...but did you ever get a front end alignment after all that suspension work?
Some people overlook that and having it all aligned makees a huge difference usually.

 

Yes, when I finished it the car was way out of alignment as expected. Got it aligned at Sears and everything was cool until I decided to see what she really had .... which was just enough to kill an axle .... now all these probs

Called Pepboys today. $69.99 + $50 core ea for remans ... they don't have new ones.

 

So.... my cars just sittin in the garage on stands .... bein a POS .... I wish OBX/BLOX would hurry up and copy some raxles for me ....

 

UPDATE: So I got a chance to talk to the store manager and told him the whole story and that I was less than satisfied with not having any cores to turn in elsewhere and so he refunded me $45 for ea core

So I went to another AZ location and they ordered me some NEW ones no problem ... supposed to be here tuesday

 

Awesome. Hopefully the new ones stop your shaking.

 

New axles are in and car runs smooth

Just nice smooth acceleration with some turbo hissing, then a bump in the road, and some scraping sounds

 

What are the scraping sounds?

 

lol ... my car is too low... I think its the tow hooks scraping the road ... I am gonna try and get my KYBs swapped into it to replace the stockers and see if it gets better , but I might just have to raise it up some ...
