Hey guys! I'm new to posting here at the forums, but I have used your website many times to answer the toughest of my Camaro restoration questions. Here is a tough one, at least from my perspective. I have a 1969 Camaro with a mono-leaf setup and a 10 bolt rear end. Needless to say, that just won't cut it! Smiley So I purchased a Hotchkis multi-leaf setup along with the many other goodies to get rid of the mono-leaf setup. No problem installing. I purchased a 12 bolt rear end with casting number 3969341, which is stated in other forums as a late 1969 Camaro rear end or a 1970 Nova rear end. The rear end is built and ready to go, I moved the mounts to fit the new multi-leaf springs, but here is where my question comes into play. On the rear, I have 15" Torque Thrust D wheels that are 7" wide with a 4" backspace. The 10 bolt I took out is 1 inch shorter in width than the 12 bolt I am about to replace it with. This will increase each side by 1/2" by my calculations. Will the wheels and tires stay inside the fender well? Or will they rub? Feel free to correct any errors I may have made while typing this, and thanks in advance for your time! -ChALkY

I have a 69 Z28 with stock rear end.  I heard a sound like it was a loose wheel.  When I jacked the wheels off the ground I discovered that the entire axel is moving slightly left and right.  Any help on what could be the problem?

Axle bearing about to come apart would be my first guess.

Do you have any shop manuals? I always start by removing all the brake parts.  Remove the cover plate on rear housing. Remove bolt from cross shaft push cross shaft out. Push in on axle and you will see the "C" clip on the end of the axle. Slip the clip off the end of the axle. Pull the axle out of the housing. If it's a bad bearing it might be kinda hard to pull out but it will come.

Becareful not to turn the rear end much with the cross pin out, the spider gears can shift, you also need to replace the pin after pulling the axle until such time as you are ready to reinstall it, then remove it again slide the axle in put the C clip in pull the axle outward to seat the C clip and reinstall the pin and torque the retaining bolt. Look up the torque, cause I don't think it is very much, cant remember exactly, maybe someone will chime in with the specs.

If the axle is hard to remove, I hook a chain to the lugs and the other end around a sledge hammer. They make an axle puller but the chain works.
