5 Speed XJ 4.5" Lift Driveshaft Question
I'm running a 98 xj with a manual trans. I've heard that the 5 speed trannys are shorter than the automatic ones. I have a 3" add a leaf in my rear spring pack and a 1/2" lift block with a 3 degree pinion shim. The driveshaft was vibrating under hard acceleration so I dropped the t-case. Question is, if I opt to lift my rear end another 1.5" with a shackle, will my vibes come back? At 4.5" a sye is questionable. Some xj's need a sye at 3" some have 5+" of lift on a slip yoke. Should I try it and see what happens? I'm on a budget big time or I'd get a sye in a heartbeat. Input please.

If I eliminated the slip yoke do you think an IRO hack n tap would be suitable since its cheaper and fairly easy to do? The jeep is a daily driver more than a toy so it's not going to see trail abuse much

Save yourself endless headache and install a SYE from IronRock and a front XJ driveshaft. The angles of the stock set up at 4.5" will eat u-joints.
Yes, a manual is a little thinner than an auto but the stock front shaft should still work. They are generally 31"
Also a Dana35 has a smaller housing than an 8.25. Again adding to driveshaft length.
The hardest part of a hack-n-tap, is drilling at perfect center of the output shaft.
The output shaft is much easier to cut with the engine running and in Neutral or reverse. I removed front drive shaft also when doing this.
Good luck

I'm sorry I should have stated I have the 8.25 rear. Thank you for the info. I will probably get the sye in the near future. Working part time in high school still it's hard to build up the funds. Plus build my 84 Chevy pickup. Just spend 2500 on wheels and 39.5 Tsl's haha

Also, Grand Cherokee's have a longer front DS by 1" or so.
Here are some current links. I just got one for $50 shipped.

Thanks man you've been a big help. I'm going to order those shackles up tonight and hopefully get em installed by next weekend to see how the driveshaft acts.

Have you pinpointed the vibes?
Remove the front Driveshaft and drive it to check for vibes.
Remove the rear DS and drive it. ( I drove up to 60mph on the front DS).
This will narrow it down to an individual shaft and its issues can be addressed.

No I currently have a 3" add a leaf and 3 degree pinion shims under my springs. I ordered the 1.5 shackle to make my total lift 4.5". Then I will see how the angle on the shaft is and probably buy an IRO hnt soon. I need a water pump now though it crapped yesterday
