Control arms or new drive shaft?
 
Hi guys,

As you can see this is my first post so please be gentle :D

I recently lifted my JK from a 3" to a 4" lift and installed 3/4" coils spacers to level it out. (4 door, manual)

I believe that my front drive shaft is sitting at too steep an angle for it to last.

I do have to get new lower control arms to correct the caster but would I be able to correct the drive line angle by installing adjustable upper control arms?

Alternatively should I do the upper and lower arms and get a new drive shaft.

I would like to get the setup correct but I would rather not waste money that can be used for other mods.

Your input would be appreciated.

So you're what...almost 5" high? To be honest, I'd do control arms, trackbars, and replace the driveshaft joint. That's some serious lift for a JK what the hell size tires are you running? That driveshaft might be the LEAST of your worries

also, welcome to WF! we're all here to help and learn

First off which lift did you go with? Second how much time do you think you will be spending off road?

Thanks for the welcome. I'm sitting at 4" rear and 4.5" in front. I already have adjustable track bars front and rear.

I am running 35's but they were rubbing at full articulation, hence the 4".

Why do you say the "least of my worries" what else can go wrong?

The kit is the 4" zone with a few extra items as above. I do a fair bit of off roading and generally go a bit wild when I do.

CruserBruiser 03-15-2010 09:20 AM

well in that case your probably gonna need both of those items, I would do the control arms first and I wouldnt replace the drive shaft until it broke.

I was thinking along those lines.

Will anything else break if the drive shaft breaks ie transfer case?


Just for interest sake, and it's fun to post pics :)

Good looking JK! I'd expect the DS to give you some warning before it just gives way . . . at least mine did . . . honestly I'm not sure how my rear stayed together based on the noise it was making when the CV went bad, but it held together. A broken DS could create quite a mess if it actually broke and was flipping around under there. I'd also go with new control arms first.

GroceryGrabber 03-15-2010 11:06 AM

Dude, your Jeep looks AWESOME! I love it! The seats with the color is very nice, and those tires are serious :punk: very nice Jeep.

The reason I said "least of your worries" was because alot of times with that much lift you'll see people stuffing 38" or higher tires. At that size, the axles are going to need addressed or swapped. You've got 35's however. Control arms and driveshaft joint are going to be the problem spots.

It's not really needed, but if you wheel hard some chromo shafts for your front D30 are a good idea, possibly a new beefy housing cover. Like I said though, neither is NEEDED. I'm getting some 35's soon, I might get the stronger housing cover for some piece of mind that gears are better protected from axle flex, but I'm going to hold off on the shafts and see what happens. It's all up to you.

I have to mention it again, nice job on that Jeep. It's probably the coolest 4 door I've seen so far. :cool:

Thanks Schmo:D I'll keep any eye, ear out for any strange noises from the DS. Strangely the rear shaft angle looks perfect.

Thanks GroceryGrabber, other than the increased capability, the compliments always make it worth while. 2 1/2 years and the grin is still there.

I will be strengthening the front diff as soon as I rebound from the regear $'s.

I wanted to go with 37's initially but after researching them with a Dana 30 i will stick to the 35's.

Thanks again for all the help and compliments:wavey:

That's one of the cool things about the 4 doors and even LJs . . . the rear DS is quite a bit longer . . . on my TJ the rear DS is pretty darn short so the angle is pretty steep, even with just 4" of lift. Are those pics from South Africa? I'd love to see more!!!

scopop 03-15-2010 01:39 PM

Very nice Jeep!
The trend I’m seeing where I live more and more is less lift and modifications to fenders or wheel wells to avoid the added drive train stress of lifts over 3 inches. Flat tube type fenders give you another 2 inches of clearance for full articulation. I’ve seen JK 4 doors here with 2.5 inches of lift, sway bar disconnects and 35s fully flexed and not rubbing. Of course low lift has it’s problems too. It normally means full skid plates and a tummy tuck if you are crawling, because you will end up dragging something.

Thanks Schmo, yeah it is SA. I'll take the risk of highjacking my own thread and post some more photos.

I did consider going with the Bushwacker flat fenders but I was still rubbing on the sway bar links and on the inside rear wheel arch at full articulation.

I am not sure how the guys get away with a small lift and big tires unless they have even less than 4.5" backspacing.

Funny you mention this, I've noticed that as well. 2.5" lift, flat or no flares, and 35's. It doesn't look bad either. It gives the Jeep kind of a solid, hulking look. I'm also seeing 33's on JK's with no lift, just flat flares. Same look.

Last week driving home from work I even saw a TJ with 0-2.5" lift on 33-35" tires and flat flares. I couldn't tell since we were passing, but that thing looked like a beast. I'm considering this. It looks boss, has minimal mods, and little to no drivetrain issues.

Won't look as good as the OP's, but still.

Jeep4fun 03-15-2010 02:39 PM

Sorry mods :D

If I had to do it all over again I would go the minimal lift, max tires, flat fender route. To me the Lower40 JK just pushes my buttons.

This jeep thing never ends does it?

Man it doesn't. There are just so many different routes you can take to get to the same finished product with these. Suspensions, body lifts, rims, flares, tires...it goes on and on.

I'm right about to start my build, just waiting for a little warmer weather. You'd go 2.5" lift with 35's and flat fenders?

The nice thing about your setup is you've got flexibility. You can increase tire size if you please with basically just an axle mod or swap. Then you could add flat fenders and really go to town lol

sweet pics! Be careful wheeling you don't hit a monkey or something :rofl:

I am very happy with my setup, a bit of tweaking here and there still but that's the way it goes.

If I had to do it again I would do the 2" or 2 1/2" lift with 35's and the flat fenders. Just to be different.

Yeah you have to watch those monkeys and don't drink water from puddles :eek:

Schmo 03-15-2010 04:00 PM

Awesome pics . . . I've heard that you don't want to drop the soap in jail, now I know not to drink out of puddles if in Africa :D

Has anyone tried these to improve the angle of the front drive shaft when lifted?
