Help with front end work... ball joints, u-joints

I am swapping out my dana 30 3.07 for one with 4.10's. I want to change the 297 u-joints on the 4.10 axle before I put it in. Possibly the ball joints to.

1. What is required to get access to the u-joint to take it out?

2. Do these u-joints come out and go in like any other one on the vehicle except that the snap rings are on the inside instead on the top of the cap?

3. Do I need to remove the ball joints so I can remove the wheel assembly to get access to the u-joint?

4. Whether I need to remove it or not how are ball joints removed on a 95 YJ and do I need ball joint fork to pry it out?


Please give me some input on these questions so I can figure out my plan and what parts and tools I should go get. Thanks

Does anyone know how to get the front axle U-joints out and what has to be removed to get to them? And how to change ball joints?

To get to the u-joint
1. pull the wheel off
2. unbolt the brake caliper.
3. remove brake disc.
4. unbolt the three bolts holding the hub to the steering knuckle.
5. pull the hub off. (the axle shafts come with it)
6. change u-joint as usual.
7. put back together.
8. repeat other side.

I am not sure about the procedure for the ball joints but you will need a BFH or a ball joint press.

Hey does anyone know what the size difference between the 297 & 260 u joint are, so I can tell whether I am really buying a 95 or older axle?

Also how to tell if its a 4.10 ratio?

Please if someone could answer these ASAP (tonight) cause I am going tomorrow to get it and may not get a chance to look at any replys tomorrow.
thanks

Dunno where the axle is, (outside the vehicle or in), but you can rotate the tire 360*'s (if you need to, you could probably just mark one of the wheel studs) and see how many times the driveshaft spins (or yoke if no D/S... should be a little bit over 4 rotations).

Look for a tag, people say do that but any tag I ever see I cannot make out...

Yah its out of the vehicle.. I suppose I could just rotate the wheel hub and see the turns of the yoke. Thanks

Any input on 297 vs. 260 size or how to tell by looking at it
edit: I think I found something for the u-joints. 260's are 1.06" diameter and 297's are 1.18" cap.

hey another question: I have a 95 so I have 1330 u joints in the rear driveshaft. What would I have in the front driveshaft? 1310 or 30?

I was looking in the Quadratec catalog at replacement ujoints for the front D.S. and they are listed as Spicer brand, year 1945-2005 wranglers front or rear u joints (153x) 3-7/32" wide from cap to cap.

What is 153x ? I thought the u joints differ after 1995 but they seem to say they are the same for all. Any explaination on this?


ALSO, should I spend the money on a u joint/ball joint press or will a C clamp and sockets work just as well?
