Hey everyone i got a 9 bolt rear with the aluminun driveshaft. I purchased u joints from local parts store thinking they were the correct ones well pressed in the new ones went to put it back in and the rear is to small litterally can move the back of the shaft up amd down while the retainers are bolted and torqued down does anybody have the correct part numbers for the u joints that go in the aluminun driveshaft i mostly need the rear u joint part number

 

My info shows 1988-93 camaro/firebird.... All with alum. driveshaft.

Neapco 3-3130 std.,3-3130BF HD or 3-0544BF HD premium alumiguard rear
Neapco 1-0153 std., or 1-0626BF HD front

3-3130 is a conversion U joint that puts a 3RN Joint to a 1310 Joint
So it should be two diff sizes.
One side of the joint will have 1.063" bearing caps (the 1310 side) with a 3.219" outside lock span.
The other side of joint will have 1.125" bearing caps (the 3RN side) with a 2.556" inside lock span.

 

My factory 89 350 TPI had a steel shaft.

Come to think of it, my brothers 93 LT1 TransAm had a steel shaft too.

Soar,
It would help if you listed the part number you were given, along with the manufacturer.

Rock Auto shows no ACDELCO part number for the Axle Joint. Shows loads of other manufacturers though.

For example,
SKF Part # UJ372
Rear Joint; w/ALUMINUM DRIVESHAFT; Base Model

or

GMB Part # 2400356
Rear Shaft Rear Joint; Grade Standard; Lubrication Type Grease Fitting in Cross; Aluminum Driveshaft

or

NEAPCO Part # 33130
REAR SHAFT REAR JOINT - STD - w/ALUMINUM DRIVESHAFT; Base Model

 

I used CarQuest 3-3130 on my 85 IROC.

The u joint that i got was moog u joint part number 369

Another that im looking at is a moog u joint 372c this one is for aluminun shaft that goes to the rear axle

The fromt one is correct its just the rear u joint im looking for

 

That's what I replaced with the 3-3130.

Best of luck with your quest,

Yea but was your rear pinion yoke on a ten bolt or a nine bolt rear

 

I posted what you need..

Yes the moog 372c is the correct one.

Your 369 is a straight 1310 U joint..

You need a 1310 to 3R (also known as S44) conversion joint.

The driveshaft uses a 3RN and the 9 bolt pinion yoke is a 1310.

Here you go... These are all the correct part #s for what you need.

372c is for the aluminum drive shaft to 9 bolt pinion yoke awesome..


what about the front of the aluminum drive shaft to a steel slip yoke?
