getrag 282 jackshft lengths

[ga2001532]

i have had my 3.5 getrag 282 swap done for about 20,000 miles and recently its not liking my cv that i have been using. started getting some vibrations and turns out the grand am passenger cv that i have been using is about an inch or so short. i have boughten a 2006 g6 3.9 cv which is a perfect spline match but it is also a inch and a half to short. did they make any longer jackshafts then the 1990 beretta 3.1 jack shaft that i have been using. tomorow am picking up a 2001 manual grand am shaft which might just be long enough but am afraid that also will be a inch short. this shaft is 37 inches long and wouldnt use a jack shaft, but if that turns out to be to short am out of ideas. my only next idea is go to the junkyard and see if i can find a longer cv shaft to mix and match my cv ends on to make it work with the jack shaft i already have.

i dont have the funds to get a custom one made or really the time. their are a couple 90 grand prix jackshafts close by but am not sure if those are longer.

if anybody has some ideas i would appreciate it.

All the HM282 jackshafts are the same length.

You'll have to mix and match to get a CV that fits right.

I know their are alot of smart people on this board. Since you can't buy new Jack shafts or barely even used ones. Everyone I've came across has a bad sloppy bearing. I want to use a pillow block type bearing in place of the old bearing. I will do what ever it takes to attach the bearing but what I'd like to know is how fast does that shaft spin. Don't want to go through all the working redesigning that shaft for it to fail. Basically all I would need is a mount to the motor then the pillow block bolts on to that. Just need to press fit the bearing and a set screw.

The jack shaft should spin as quickly as the wheel does... Calculate that based on wheel/tire combo and how fast you drive.

Incorrect.

The Type I jackshaft with the cast aluminum housing is a different length than the Type II which does not have a housing.

Find a Type II jackshaft. It has a sealed bearing which can be replaced.

I have a Type II shaft on my Fiero. I'm using the right hand axle with the left hand inner joint from a Pontiac 6000 with JA2 heavy duty brakes and 4 speed automatic.

Fiero has a Caddy Northstar with 282. So far I've broken both the cup and tripod on the left inner CV, but have not had any problems with the jackshaft and right axle.

I had both and compared the lengths... They were the same.

the ~87 ish Beretta unit was the exact length as the stock one from my 91 Z24. I used the factory GM Cavalier axles as well.

[ga2001532]

how do you replace that sealed bearing. i have the none aluminum housing shaft. just a solid shaft with a bearing. i have never seen a replacement for that bearing.

[Superdave]

You'll have to take it to a local bearing place.. they are harder to find these days but there is usually one close to most larger cities. make sure to get one made in the US and rated for the speeds.

I replaced one that I did an engine job for the guy... Parts I used.

Does this also include the jackshafts used on the '88-90 Grand Prix? I was told that the Grand Prix jackshaft was 2 inches longer than the Beretta / Corsica / Cavalier jackshaft. But I'd like to get a second opinion.

o man the one i got isnt even close to that strong. its a completly different design. i will try and get a 88-90 shaft,
