Tc drop pos -- sye??
I installed a 3" lift on my jeep and now I have vibrations at certain speeds. The vibes are not horrible -- definitely drive-able -- but I want to fix the issue the correct way if I can...
I tried a TC drop. What a piece of ****. It literally did nothing for the vibrations and made my shift linkage have an incredible amount of tension. I couldn't even adjust the linkage bc of how rusted it was. So I ripped the TC drop out right after installing it. The studs on the cross member were seized too. Complete waste of my day/time. So now I am looking to do an SYE. What's required? I don't know much about drivetrains. I read that I need to measure the length of something and a company will custom make a driveshaft for me or something? What if I choose to go higher in the future? Do I need to get a NEW driveshaft again? I want to do this once. I want to do this the most cost effective way. Whats the best bang for my buck? I'm not interested in a HnT either. Just an SYE and let's get this thing rollin' smoothly again. Thanks guys. |

I'm running about 5.5" of lift with a factory ZJ front shaft and have zero issues. |
For a 3" lift a factory front shaft rebuilt with large joints will work fine for you. In fact it's not bad idea to replace the joints in your front shaft at the same time than it's all new. When installing the SYE check the TC chain and gears while its open.
Just a note but I have the RR SYE installed in mine that I bought on a special for $99 several years ago on eBay only 3 of them. It looks exactly like the AA's as far as I could tell, works just fine. I didn't install my SYE till I went to 4 1/2"'s of lift though, I was good at 3" with a TC drop kit. I do have shims on the rear differential that were needed. |

I didn't have any with the 3" lift.

Do the SYE. I have the special guide they recommend using to drill the hole as well as the bits and tap. Your welcome to use them. Will save you quite a few bucks. Cutting the output shift is very simple. I put mine in drive with both drives shafts removed and just held the cutting wheel straight. Makes a nice clean cut.

What degree were the shims that you used for the 3" lift without the SYE?

Best way to figure out what shim you need is to measure with an angle finder. I went with a 6 degree shim and it worked out perfectly.

If I have a 2000 Jeep Xj automatic, then I have the 231 transfer case right? So I would order the AA SYE from lets say rustys for $200. Then pick up a front driveshaft from which year xj? And then I would have to put special u joints on the donor driveshaft? I need to know every single thing I need to buy please. I want to do it all in one day. I watched a video of the install and it doesn't look bad at all.
I don't want to do the tom woods driveshaft. Just a stock front from a junkyard jeep. I'm fed up with the vibes and was going to just shim the axle with the stock drivetrain but I've come to the realization that the driveshaft angle in stock form is at too extreme an angle to be shimmed back into place... I rather spend the $3-400 and do this and get it done I'll be installing myself with a friend. I have basic auto mechanic knowledge. My friend builds cars from the ground up so we should be fine I think |
Bump. Guys can I install any year front driveshaft from an automatic Cherokee on the rear of my 2000 XJ with an SYE?
Does it matter if I have the D35 as opposed to the 8.25? Will a front driveshaft just simply bolt right onto the rear after installing the SYE? |
From what I've read and seen you can use any front drive shaft from an XJ. I also read that the ones with auto tranny's have a slightly longer front drive shaft and when you do the sye the front driveshaft will bolt right up. Because the transfer case yokes for front and back match after doing sye. You should look into the hack-n-tap sye you can get them for $100 and $50 max for a driveshaft from junk yard. I've seen people running 35's pretty hard on the trail with that same set up and worked great for them.

my jeep is currently at 3inches of lift and im going to 4.5inches in three weeks but before that I have to have the iro hack n tap installed since my rear drive shaft got lost on the high way. my question is would I need to change anything driveline wise since I am adding another 1.5 inches.
