robfg67 Posted September 29, 2008 Share Posted September 29, 2008 Can this axle be swapped with my stock Dana 35 fairly easily? Would I need weld perches? Would I need to change splines? http://cgi.ebay.com/ebaymotors/ws/eBayI ... Track=true Link to comment Share on other sites More sharing options...

Would I need to change splines? http://cgi.ebay.com/ebaymotors/ws/eBayI ... Track=true You would need to weld in new perches, they are not the same width. Also, the 97+ 8.25 is more desirable.

robfg67 Posted September 29, 2008 Author Share Posted September 29, 2008 Why is the 97+ preferable? What about the spline? I'm quite a newbie with this! Link to comment Share on other sites More sharing options...
Pete M Posted September 29, 2008 Share Posted September 29, 2008 The 97+ have 29 spline axleshafts and are stronger. But the 8.35 in the earlier 27 spline count version is still a bit better than the Dana 35. If this gets you a better gear ratio, I'd do it and then score the junkyards for a disk brake swap. :D Link to comment Share on other sites More sharing options...
robfg67 Posted September 29, 2008 Author Share Posted September 29, 2008 My stock gears are 3.07, so if the price stays reasonable, I'll bid on it. Also, it's only about 40 minutes away. What is the 'going rate' for this axle and what vehicles would be the best donor for rear disk brakes? Link to comment Share on other sites More sharing options...
Pete M Posted September 29, 2008 Share Posted September 29, 2008 Personally, I wouldn't pay more than 100, maybe 150 for one in good shape. For disks, I believe it's the Grand Cherokee that is the best fit? Someone correct me on that if I'm wrong. Link to comment Share on other sites More sharing options...

Someone correct me on that if I'm wrong. yup, ZJs or WJs. and ya.......$100 tops IMO. if it were a 29 spline or had a LSD then maybe more, but I can find 27 spliners for $150 all day long, so theres nothing really special about it.

Pete M Posted September 29, 2008 Share Posted September 29, 2008 I thought WJs had the wrong wheel bolt pattern? Link to comment Share on other sites More sharing options...

robfg67 Posted September 30, 2008 Author Share Posted September 30, 2008 If I win the auction & swap the rear axle, can I just change the gears in the front Dana 30 stock axle to match? I don't plan on doing any off-roading. Link to comment Share on other sites More sharing options...
Pete M Posted September 30, 2008 Share Posted September 30, 2008 How recently have you done the brakes on your Dana 30? You can find Dana 30s in the junkyards with 4.10s already in them. Link to comment Share on other sites More sharing options...
CWLONGSHOT Posted September 30, 2008 Share Posted September 30, 2008 Swapping to 29 splines later is easy of the axle is open. The CASE/HOUSING on the 8.25 is where you are gaining stregnth over the D35. Its a worthwhile swap, I agree with Pete. CW Link to comment Share on other sites More sharing options...
robfg67 Posted September 30, 2008 Author Share Posted September 30, 2008 Pete, the pads are new and the rotors are good. Would this disk brake conversion write-up apply to this 8.25 axle? http://www.links4jeeps.com/writeups/d35 ... index.html Link to comment Share on other sites More sharing options...
Pete M Posted September 30, 2008 Share Posted September 30, 2008 Pete, the pads are new and the rotors are good. I ask because there are some changes in the brakes in the axles over the year. But even so, I still recommend a junkyard front axle. Regearing on one axle can cost $250-300 or more to accomplish. Link to comment Share on other sites More sharing options...
Eagle Posted September 30, 2008 Share Posted September 30, 2008 ZJ or WJ? ZJ WJ used a different bolt circle, so you'd have mismatched wheels. Libertine also used a 5 on 4-1/2" bolt pattern, I think. Did they offer rear disks? Link to comment Share on other sites More sharing options...
Pete M Posted September 30, 2008 Share Posted September 30, 2008 There are rear disks on my Dad's 06 Libby. It's a Limited though, so I can't say they are all disks. Link to comment Share on other sites More sharing options...
Sir Sam Posted September 30, 2008 Share Posted September 30, 2008 :hmm: The hardware such as the calipers and backing plate are the some, the rotors, obviously, have a different bolt pattern - but you take what you can get when you can. ZJ or WJ? ZJ WJ used a different bolt circle, so you'd have mismatched wheels. Libertine also used a 5 on 4-1/2" bolt pattern, I think. Did they offer rear disks? I wasn't talking about grabbing the whole rear end, only the expensive to find brake hardware, and buying new rear rotors. There are rear disks on my Dad's 06 Libby. It's a Limited though, so I can't say they are all disks. The disk rears are not limited to the limiteds. All KJs over 03(i think its 03) had the rear disks. i had the oppourtunity a while back to pull the rear brakes off of an 06, I sure wish I had done it then, they would have been perfect for my 01 8.25.

Eagle Posted September 30, 2008 Share Posted September 30, 2008 You can't count on mixing calipers from one application with rotors from another application. Heck, you can't mix parts from different years of XJ/MJ front axles, and you want to start mixing from different vehicles? Not gonna happen.

robfg67 Posted September 30, 2008 Author Share Posted September 30, 2008 I plan on heading out to my local JY this weekend...so should I be looking for ZJ rotors & calipers? I've never seen a Liberty in a JY. I'm aware that I also need to bring the axle somewhere to have the perches welded on. Do I need different leafs for this axle for a SOA? If so, is Motion Offroad a good source for new leafs? Lastly, what is all this talk about splines. Will I also need one of these too? Link to comment Share on other sites More sharing options...
