I'm sure he meant the Rod Ends need replacing but with that much rust you might want to replace the whole arm at this point.

So are those called control arms or long arms......also would you reccomend a brand to buy?

Your picture shows the lower control arm. It could be a short arm (mounts at the factory location on the body) or a long arm (the factory body side mount is cut off, and a new one is welded on allowing a longer control arm).

If it is lifted 3-5 inches, you really could have short arms. Take another pic that shows the mounting point on the body. That will allow us to see if these are long arms or short arms. If the arms are solid stock, you can just wire wheel them, apply some new paint, and re-build the joints. I think your joints are different from the heim shown above, but I could be wrong. Post a picture of the joints. With all the rust, It is very likely that your joints need to be rebuilt or replaced.

In regards to the rear driveshaft, what is wrong with yours? Is it bent or out of balance, does it need new U-joints...

Rather than buying a new one (very expensive), it is usually better to find a used one at a salvage yard or have a local driveshaft shop build one. I don't know if the driveshafts are the same length on grands with the 247 or the 242, maybe someone else will.

those look like the old Teraflex LAs, you could get replacements from many places like IRO or Ironman4x4

Yep, I just grabbed a picture off of Google to show the OP what they generally look like.

here are some more pics one is the ones on the back, i measured the front one to be around 31 in if that helps i also can take a video and post it to youtube if needed. Can you buy new bushings for them because they are solid, not rusted throught but the bushing are just wore out bad to where you can move them.

That has to be one of the biggest draw backs of living back east(ohio) is that rust!!! Looking at the pic's you have no bushings left, how was your DW? I think I would buy some new upper and lower arms,

yes the driveshafts are different lengths depending on transfer cases and engines.

Those joints look rebuildable. It looks like you can spin the two outer peices off, replace the bushings, and re-assemble. I would soak the joints in something to remove the rust before doing that though.

Could those be Rock Krawler long arms? I don't know what all of the kits out there look like, but those look like or are very similar to RK joints.

I wouldn't buy new control arms unless the rust has penetrated to the point where it has weakend them and they are unsafe.

If those are RK arms, they are solid stock. Just sand the rust off and re-paint. If they are the RK arms, here is what the joint looks like on the inside:


From the center out on each side on RK joints: The pivoting ball, a poly bushing, a thin metal washer like ring, the outer ring the screws into the joint housing.
On some of the RK kits the spacer is attached to the ball, on other kits the spacer is separate and will fall out when you remove the bolt. The joints pictured have spacers that are not part of the pivoting ball in the middle. The rest on each side of the ball and are held in place by the bolt through the joint. They fall out when I remove the bolts. You just use a pair of vice grips to twist the joint ends off and access all the interal parts of the joint.

Even if they are not RK arms and joints, they are probably something similar. Even if you decide you don't want to rebuild them, you should be able to buy whole new joints that screw into the arm and replace what you currently have. Even if you wanted to buy a different style of joint, you could. Just make sure to measure from the center of the eye on each end of the arm. After you install a new joint on each end, you want to make sure that the arm is the same length (unless you want to adjust the arms, pinion angle, or alignment.

They look like Rock Krawler's Krawler joint to me too. If you can unscrew/remove the current rod ends it'd be easiest to just buy new ones and screw them into the arms. Rock Krawler Catalog
