No, you need new bearings and seals/ crush sleeve and shims with the install kits. It would be very dumb to install used bearings and reuse parts in an axle, IMO.

Besides, when you install a new ring and pinion you have to RE shim everything.

 

Hell Iv got 35s on a d35. Iv beat on it lightly and so far so good (knock on wood).

 

I've seen a super 35 kit handle lighter 35's alright. Lots of driver technique.

I wouldn't ever personally out any money into one.

 

And don't lock it.

 

I forgot about the re-shimming. These jeeps are like plumbing. If you mess with it you might as well replace it....

What size gears would you recommend for 33 inch tires? I want to regain my lost fuel mileage as well as performance off road.

 

Im not putting money into mine 35s are temp tires 37s will be next with new wheels as well full widths or at least a d44 if I get lucky enough to find one.

 

4.56's and my 33x10.5's have a good bit of power, run a little high on the highway, but I speed. A bigger 33" or 35" would be perfect for me, so I'm going 35's soon.

 

So 4.56 gears with an auto transmission is the way to go with 33x12.50's.

I think there is a shop up the road from me that is a Yukon rep/dealer. I will give them a call and see what they would charge for a gear swap. Maybe I can get enough tax money back next year to get this done.

Getting tired of the bad gas mileage....

 

Fellow XJ brethren, I think it is time to start planning ahead!!! Right now I have a budget boost (3" front spacer, 2" lift shackle) on my XJ, these were purchased because of price and I had to get the Jeep off my new tires because they were rubbing. With all that said I now have seen the err of my ways , the ride quality is horrible and I know those spacers won't last forever, but I want to use this time to my advantage and prep my girl for a bigger full lift (looking for a 4.5" lift this time) and I want to know what I need to get done to the Jeep before I install this lift. What upgrades would you all suggest that I do before installing this lift?

 

4.5" lift requires:
Front lift springs
Rear lift springs (with extended shackle if desired)
Lower control arms
Upper control arms
Track bar
Sway bar links/disconnects
SYE & driveshaft
Front and rear brake lines

 

*shocks
Also, sye is debatle if its required, but if you can afford it from the get go, do it

 

So I will need a new driveshaft when I install a SYE? I have been eyeing up the Zone Offroad 4.5" full lift kit.

 

If you get a sye you will need the double cardan shaft, most often if you check eBay you can find a decent deal on a decent sye kit and driveshaft combo

 

I will keep any eye out on ebay. I would like to have all major upgrades done before I go to install the new lift in the Spring.

 

Thanks, forgot about shocks. I'd say wait and see at 3", but it's almost certain he'll need it at 4.5". It's a '99.

You can use a stock front DS in the rear once you get an SYE.
