Sye install - please help

Ok folks - we are going to attempt our first install of a SYE and CV driveshaft on our 94 YJ 4.0 5speed manual. i was watching a few videos and everything is pretty cut and dry. however i got a little nervous when they mentioned the pressing of the needle bearings. we have done all our own mods on our jeeps and not afraid to tackle new things. if we get into this case and find we have the NP231 with needle bearings how hard is it to remove them? do you need a press? any info and or video links would be a huge appreciation.

thank you..

Well i agree with needing a press, it takes less than 30 sec to press them out. I did mine at work and it took that long to press them off. Imo the sye is very simple to install I just had issues with bad shift forks and pads, other than that it was easy.

I rebuilt my TC and I picked up a 20 Ton Press from Harbor Freight a year or so ago. They have it on sale now and I got mine at the same price.
$249...on sale for $199...20% off coupon...netted out around $160.
It made it a piece of cake to replace all the bearings and seals.

I also made a brake for it so I can bend steel. I needed to fabricate a plow frame setup, basically copied a Meyer setup. I adjusted it to compensate for the lift. It paid for itself 3x over just on that one project!!!

A great investment as a Jeep owner!!!

Hey Glen91 - i like your press idea and using it to fabricate bent steel. thats cool!

we got the SYE installed and put the TC back up in the jeep, bolted up the skid pan, bolted up the front driveshaft and when we got to the rear drive shaft we found - oopps its too long. we called the legend Tom Wood. he was soo cool over the phone and we gave him the measurements and he said no problem he will make the new shaft the today and ship it out over night. huge props for his support. he is the man!
