Axle shaft problem
I have a 90 formula with a horrible grinding noise from the rear axle. I lifted it up today and checked out the yoke and it seemed pretty tight. However I can take the rear tires and move them in and out towards the pumpkin. Is that normal or is there something that should be tightened or maybe just replaced with another axle.

Re: Axle shaft problem
the axles will move in and out a little.
you should jack up the car and pop off the diff cover, see what going on. maybe you blew it up, or it leaked out all the oil, and its about to blow up

Re: Axle shaft problem
Which differential do you have? If it's an Auburn then the axle end play will increase as the Auburn wears. Replacing it is the only way to reduce the axle end play. If you have a standard differential and you have been doing a lot of one wheel burnouts then you might have worn the differential case and thrust washers, which will cause increased axle end play.
The noise could be from a bad bearing.

Re: Axle shaft problem
It is a standard 2:73 axle..and that sounds like it might be it. I bought the car from a kid that must have beat the sh*% out of it. Well the price was right so I guess I can now shop for an axle with 3:73's.

Re: Axle shaft problem
What do you mean about other considerations? Camaros and Firebirds are very hard to find in MD that are not already picked apart of the good stuff. I think the 3:42 V6 rear end for $69 is a steal.

Re: Axle shaft problem
Where is the speedo gear located? I have never done an axle swap on a third gen so I have no idea! The pick n pull near me charges $69 for ANY axle you can find, but the 89 IROC Posi is gone lol.

Re: Axle shaft problem
drivers side rear at the tail of the trans.
you will see the cable or plug (depending on the year) at the tail of the trans.should be one 10mm with a hold down pull that out and grab the gear,it will slide off the speed sensor.
a good cordless sawzall should be all you need to get the rear out of the car at the yard

Re: Axle shaft problem
As the link I provide mentions, you may have problems with the drive and/or driven gears depending on what ratio your current rear end is (and there may or may not be a VSS, again depending on year); there is also the possibility of combination valve and parking brake issues. Good luck.

Re: Axle shaft problem
Thanks james.. I read that page a few days ago and I am hoping that everything will be the same on the axle since it is an 89 and my car is a 90. I will grab the drive gear in the tranny to go with it.

Re: Axle shaft problem
Ok so I have a 90 and I got a 91 rear... rear end went in no problem and pulls great. I grabbed the speedo gear out of the same car and it looks the same as mine but a diff. color. Well now my speedo reads about 12 mph faster than I am going.. Any suggestions?
