Is this the start of a failing driveshaft? Picture attached. Can I upgrade only the front DS or do I need to upgrade back as well? I would like to put a 3.5 lift soon and want new DS's anyways.
Looks like it's just the cv boot is torn or the clamp isn't tight enough ... if the boot is torn and you want to put in the effort you can save the driveshaft by repacking the bearings and putting on a new boot. This is pain though and will be easier to just replace the whole shaft.
If I'm not mistaken, as long as you are the first owner the 07s come with liftetime drivetrain warranty so you can get this replaced. That way you can save the money and replace both shafts at once when you are ready.
I'm the second owner on mine too so I'm in the same boat... it may be cheaper to pull a driveshaft from a junkyard for now. Replacing the whole shaft will definitely be easier than repacking that cv joint.
But to answer your first question, for the life of me I can't imagine why you couldn't replace your front shaft with an aftermarket shaft and keeping stock on the rear for now. Mechanically it's all the same.
Yes your shaft is dying keep a eye out for how much starts to come out , some might just be from being flex out
You can not repair the stock shafts
And yes you can only buy the shaft you need , a lot of people up grade the front way before the rear
Another option is to find another stock shaft to have as a spare ( I have 2 spares and mine is thowing grease to ) so I am just waiting untill it starts to make a noise
Yup guess you are right. Seems odd that it's not available but I cannot find a boot kit anywhere for it. Which is fine, repacking bearings is a pain in the arse. Besides if there were such an animal it would probably cost as much as a junkyard shaft anyhow.
Looking at a Dana 44 with e-locker no brakes only 20,000 on it for about $650. I was one of lucky ones with the jk 07 with the d35. This 44 has the same gearing as mine.
What do you think? I still need to take a look and open it up an check the gears etc..
What year is the axle and is it a rubi rear end , no matter what it is a good price because of the locker
Just asking on the year and rubi , because good chance it will have 4.10 in it
Find the gear ratio just turn the axle flange like you would the drive shaft and count
