How Easily Will 36-37 Inch Tires Do Damage To My Axles. (Poll)

[Zebvance]

First off let me start off with some info.

 

I have a 1988 comanche 4.0,auto, 4x4 short box. I bent the front tubes on the dana 30 somehow. Not exactly sure when it happened. I was looking for a waggy dana 44 and have not had luck finding one and came across a lp dana 30 out of a 97 tj for dirt cheap. I picked up a never used OEM lp dana 30 center section with 4,10 gears to swap in for $100. This hasnt even have tubes attached or welded to it. I'm going to pick up a truss, ball joints, and u joints for it and then I'm putting it under the truck. For the rear I just put in a 96 disk break 31 spline 8,8 out of a explorer. I have serious offroads long arms, claytons adjustable track bar, quick disco sway bar links, I'm going to put on in dec with some 5100's and rubicon express 7.5 inch coils with a .75 spacer. The rear is already SOA with lift shackles and sitting at about 8.5 inches.

 

 

Now, before everyone starts bashing because Its going to be to tall, let me tell you what I'm building this rig for. I live on the coast of Texas and it is a beach rig. It is built for that. Where we go fishing is on a narrow island that is 23 miles long. there is one road on and off it at its eastern most point. The rig is made to get me all the way down to western point and back. I encounter some deep cuts some times doing this as the shore is constantly changing.

 

 

On to the point of this tread. I came across a guy that has some super swamper 39x12,15,r15s. However they measure a 1/4 inch over 36 inches. He sent me pictures of measurements. They have about 80 percent tread on them and are in great shape.He wants $500.00. remember i will be on a forgiving surface. when offroading.

 

Do yall think i shoud try it? Also will I rub with 36s and 8 inches of lift?

I'd say go for it, the 8.8 will be fine. And for what your doin down there, you should be just fine. Keep an extra wheel hub set with ya lol... Gotta love the sand.

 

I graduated from Port Aransas HS... And I know just a lil bit about sand haha

[Zebvance]

if you have answered the pole please list if you wheel it or not and what ended up breaking on it

[kolton]

Alright. Well I ended up snapping outer shafts when I started using the jeep to pull people out, and showing off. Hubs were a routine (2-3months) because I liked to play in the water.

Note that torque overload is what twists off axles. If you don't overload it,  then it will never twist off.

.

I get the feeling from your poll that you are thinking it is a matter of time (rather than a too-high torque overload event) that will cause breakage. That's like asking "how long is a piece of string?"... or more like "how many  months/years can I step on a land mine before it goes off?" - the answer is once, if you step on the trigger hard enough. 

[Timeless]

Everything will run fine (except for the gearing with 35's or bigger will be wonky) but if you get stuck, or have to pull someone else out, you are running a high chance of breaking something with 36's or bigger.

With the LP D30, you're pretty much putting in one of the weakest axles you can bolt into a jeep.

 

Sure it will work, but when you really need everything to work, like when you're stuck and the tides coming in or you're trying to help get someone else unstuck, you'll probably break something and be SOL.

[Zebvance]

Oh ok I see. So here is my next question. Should I get a set of stronger shafts for it or not bother?

[shelbyluvv]

Don't bother. That is why the TJ guy took it out. My LJ has a LP30. If I was going to wheel it I would swap it for a HP30. I did on my 2000 XJ and it only had 12,000 miles on it. I still blew up the gears on the HP30 with 35s.

 

As you upgrade axles, u-joints, drive shafts all it does is move the weak link further inboard. It ends up being the ring and pinion. I had Warn hubs, alloy shafts, CTM joints, and a custom built driveshaft.

Did he measure the tires with air in them? My buddies 38.5 swampers measure 35" aired down.

[Zebvance]

I think they were aired up. I'll have to post the pictures tomorrow
