CV axles doing engine swap

**temmakaijin** · 01-19-2014

I have started doing an engine swap on my 99 Grand Prix gtp. I have disconnected all the electronics and upper brackets. I started to try to take off my cv axles and they are rotating. The car is in park and the emergency are on!!! I don't understand know why they are turning. If anyone cud answer my question, it will be highly appreciated.

Just pop em out of the transmission.

Parking brakes only lock the front wheels and its normal for the cv to spin in lark with a wheel off the ground.

Parking brakes lock the rear wheels, not the front. And putting the trans in park stops the wheels from turning the same direction, but the differential allows them to spin in opposing directions.

Sorry typo

And most of the 4t65s ive delt with(and ive delt with quite a few) will allow you to spin the wheel in tbe air whichever direction you want(like it was in neutral)

**02NavyBlue** · 01-19-2014

Right, but the other wheel will spin in the opposite direction.

**l67ss** · 01-19-2014

Not if its on the ground

**02NavyBlue** · 01-19-2014

Right because the wheels are forced to move the same direction on the ground, making it unable to move lol.

**l67ss** · 01-19-2014

I mean if one wheels on the ground and the other is in the air(like if ur changing a tire) the one in the air will spin free.

^^^^ not if its in park.
Navy is right. If both are in air, they will spin opposite each other.
If one tire is on ground, neither will spin freely in wither direction.

Thanks very much y'all were a lot of help bc that had got me for a sec lol

**l67ss** · 01-20-2014

Wrong, ive changed a lot of cv axles and a lot of wheel bearings on 4t65 cars. On all of them(except a couple that had some custom work done) one wheel would spin independent of the other in park with one wheel in the air. And ive delt with 4t65s from 98-08.

So do u know how the park gear works in our transmissions?

**l67ss** · 01-20-2014

And actually the first 4t65 i delt with was in a 99 gtp

**l67ss** · 01-20-2014

I kno what it does in the real world

I stand corrected i misread something. Same as other auto trannies...anyways. the many GPs, 1 regal, and a couple impalas I've worked on did the exact same thing that my GP and all the rest of them does. Except yours of course, and that is when in park if both tires are off the ground, the y rotate opposite each other
