My jeep has two torn CV axle boots, so I'm replacing the axles. What else should I check/replace while I'm doing this job. My Jeep only has 78K miles. Should I replace the inner seals on the front diff? Or am I good for a while longer? If I do replace it, is it difficult? I'm assuming I'd have to drain the gear oil. Anything else to check on/replace at the same time as the CV axles?

I'm doing brakes and sway bar end links at the same time.

I generally wouldn't bother with the inner seals unless you know they're leaking. Those seals will do 200k without too much complaint if the axle hasn't been sunk in a lake.

Check the pad slides for the notches, but other than that you've got a pretty good list.

If you're replacing CV axles, it's best to get brand new ones, not remanufactured.
Check your hub/bearings for play. You'll be right there ready to replace them should they need to be.
If you're replacing calipers, I also recommend brand new ones vs remanufactured. Or rebuild your existing ones with new pistons and boots.

I'm available to assist with high quality parts should you need anything. You can PM me here on the forum or email me at kolak@aol.com

When I swapped my CV axles, also for torn boots, I used inexpensive new direct-fit replacements. I also swapped the front wheel bearings at the time.

This reply shows the parts I used to restore normal handling on my '94 ZJ.

The Moog K3166 bushings are the parts I used to press into the upper axle openings.

I'm all about just replacing the boots, more so since youre Jeep has such low miles. Whats on it is most likely better than anything you can buy today.

Its easy to find the Mopar boots on ebay. I typically snatch them up when I see them for ~$40 a pop.

$40.00 for a boot?? That's nearly as much as a complete axle assembly.

I know, Im a pretty weird dude.... I'll spend more to keep things original over just replacing stuff.

I recently bought a 98 ZJ (57k miles) and the CV boots were torn. Before I could pickup the Jeep, the guy spent $600 to have a shop replace the entire CV axle. Thankfully he had kept the original axles and gave them to me. I replaced the boots and put them back on the Jeep

I'm definitely under the impression that the original mopar cv's are stronger than any of the aftermarket (at least for stock replacements, rcv is a different story).

 

[Kolak]

The thing is, the Mopar parts you buy now are typically not of the same quality that the parts they used to assemble your vehicle. As years go by, Mopar sources parts from the same manufacturers everyone else does. No sense spending Mopar money for what is the same as other aftermarket parts. And if you did find old stock Mopar boots, they've been sitting somewhere on the shelf for 10+ years.

Did you drop a 1 off the front of that mileage 😉 or is it really 57k? 🤩

I have a lot of squeaking and clunking in my front end when I'm turning and going over blumps a air shock sound when going over bumps. Would you happen to know what it is? I had my struts replaced lower control arms and rear shocks replaced. Still dealing with noise

 

[Kolak]

You have a ZJ too? What model year/engine size is it?

Did the "air" sound start when you replaced the front shocks?

Squeaking and clunking is often the swaybar endlinks and bar mount bushings.

Air sounds has been there since I bought it 3 yrs ago. I have a mechanic. Not so great said it's just going to be like that but no other jeep owner is experiencing this. It's a 2009 grand Cherokee laredo

Another idea is to replace the cv axles with a set from a Cherokee that uses u joints instead of the cv joints for a stronger set up.

A 2009 is a WK, not a ZJ. Completely different front end. You'll have better luck starting a thread in the WK section.

57k is correct . Its a gem.

Well, let's see some pics of this gem.

It's been a while, but if I remember correctly the XJ still uses the 260 size u-joint whereas the TJ shafts use the stronger 297 size.

 

[kg6mov]

Depends on the year and options, the XJ got both u-joints through its run. Later ones are all the stronger joints, as were the ABS equipped ones.
