CV shafts going bad

So I'm 98% sure that the annoying clunk pop and vibrations from the front end on my 96 are the CV shafts going bad.

All of my wages are reserved for the bill when my mechanic gets done putting a new engine and trans in the niner.

So what are the risks running around with bad cv's? How hard is it to replace myself and how much are the parts? My mechanic said it would be "under $500" to get it done, is that reasonable?

You can replace the axle CVS in under two hours as a first timer from a write up in the faqs section. Cost for you is under two hundred.

I am doing mine this weekend I bought both of them from Amazon for $90 plus shipping. I got the CV and axle shaft for that price. There is a great write up on here on how to do it. I am also replacing the wheel bearing at the same time just because I am pulling them apart the wheel bearing assemble are $34 a piece cheap insurance as far as I am concerned.
Here is the link to the write up

The gods have decided I'm doing this tonight and tomorrow, any difference in quality of the shafts on the market? I tend to like o'reilly after having a really good customer service experience with them. Quadratech has them for $200 a side and from o'reilly they're $60, what gives?

I guess I am a cheap person, if you are not doing much 4 wheeling whit it or raising it the the $60 should be fine.

Front cv shafts are $65 a piece from O'reilly. If you are going to drive a 17 year old vehicle then it is time to learn to operate a wrench. You can replace the shaft in about 30 minutes, less if the unit bearings are in a cooperating mood. The $65 shafts come with a lifetime warranty, so if they break or the boot tears then they give you a new one.

Yeh, I'm learning to turn a wrench, haven't yet done something that much on the driveline though. Read the walkthrough and it doesn't look so bad.

Yea its not bad! I did mine last weekend and mine was popping when turning ect...then all of a sudden it was done for...took about 2 hours and not much effort at all...the whole pre assembled part and everything was 63 bucks and mine is driving great....well was until today when it got a new unrelated problem...but id do it myself!!! its not hard even for a beginner!

and the only reason mine took 2 hours is my jeep is real rusty and we had to heat bolts with a torch to break them free...you should have no problem good luck!

Well we fixed the trackbar that I sheared this morning and then we went on to do the axles. When I was at o'reilly I grabbed a 35mm socket for my 1/2 breaking bar. Both of the new shafts have 35mm nuts, the passenger side shaft on the jeep has a 35mm nut, but the driver side shaft is 36mm! What gives? We figured 1 shaft was better than none, so we hit it with some PBS blaster, stood on the brakes, threw a pipe over the breaking bar, heaved to, and SNAP!

Broke the breaking bar, damn.

Gave up, gonna hit o'reillys again tomorrow for a 36mm and a new breaking bar, then I will finally be free of the clunks.

Oh yeah, I just replaced my cv shaft the other day. I got a good deal on one from work. (Advanced Auto) Took me about 40 minutes. No clunks since

Time to invest in an impact wrench. What brand breaker bar was that?

You're not the only one that broke a half inch breaker bar trying to get the nut off. An impact wrench wouldn't even budge it! My Dad and I ended up ordering a 3/4 inch breaker bar to get it off, thankfully that worked.

kg6mov, Be careful not to strip your hub/bearing assembly bolts trying to get them off if you end up doing this yourself. Mine were rusted and stuck so I ended up cutting the ball joints and removing the entire steering knuckle with the hub/bearing assembly just to replace that stupid cv axle-shaft.

Agreed. Do it your self it'll save you a boat load. It cost me $100 for parts and I did the rest. Good learning experience too. I just used a breaker bar and a Torque wrench.

What kind of impact wrench are you using? There is no way that you are going to budge something by hand that you can't get off with a decent impact?

the cheap aftermarket axles have the 35mm nut, the factory axles used 36mm.

'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.
