I just inspected the underside and noticed a tear in my outer passenger cv boot. Given the size of the tear, I'm assuming the joint is probably near dead and worth replacing.

Should I replace all four boots and joints or stick to the damaged one? I've had the car for a few years, but unfortunately do not have prior service records, so can only assume the worst that they have never been replaced.

Btw, car is an 87 911. Thanks for the advice.

I replaced a boot once upon a time and swore never again. Next time I'm just buying new axles. Trying to figure out how the CV goes back together was a bear....fun, but a bear.

And welcome to rennlist...

I think the 87 uses fixed outer stub axles? Might be possible to replace just the boot and cv, but you'd have to somehow get around to removing the stub axle from the outer cv.

In the upper right hand corner of the page you can open a link to the entire thread. It get's good around page 3 or 4...

Given the tear is pre-existing, there is a good chance that replacement will be the only option, but you may want to assess that first.

The boots are old and tear easily. If I were to replace one boot, I'd replace them all. As mentioned above, you will have stub axles married to the drive axle on the outboard side.

The key will be to determine what the condition of the innards are. If the split is recent, and not much grit had a chance to enter, things may be fine, or they may not be. The only way to know for sure is to disassemble, clean thoroughly and then examine the ***** and race way surfaces for galling, pits and/or discoloration. If there is not, and the joint has no perceptible play, then re-packing and new boots are a definite option. I did mine, the grease can be a bit messy, but if you prepare a good, clean workspace, and take your time, you will get a good result. When you reattach the axles to the transaxle flanges, be very careful that the threaded holes are clean and grease free. New bolts would probably be a good idea too.

Thanks everyone. It looks like a job - but I'm a glutton for punishment.

As requested - here are the pics in the following order.

2. Passenger Inner:
3. Driver Outer CV Boot
4. Driver Inner


And all comments about the dirt and grime are welcome and deserved. I just relocated to Tx from the Northeast where they make garages big enough to get under a car safely so I can begin a thorough and proper cleaning.

The zip ties tell me this has been done before...

I'm going to tear into it and look at it up close. Given the zip ties (who does that???), looks like I'm tearing into both sides just to be sure.

Amber Gramps

Who does that.?.?.?.well, I've seen it before and had they used wider/thicker ones I'd be ok with it.

I've got zip ties on the small end on mine. The serrated washers can be obtained at McMaster.com, and 12.9 hardness bolts are a common item at any hardware store.
