CV Joints ???
Posted 26 November 2003 - 11:59 AM
Has anyone tried rebuilt joints as replacements ?
Is it a do-it-yerself kinda job ?
How much $$ are we talking about ?

Subaru has recently lowered their cost of CV joints so check with your dealer.
Replacing a CV is not overly hard to do. I suggest getting the latest Haynes service manual for assistance.
You need the following tools and parts
* liquid wrench penetrating oil
* 1/2 drive torque wrench
* 1/2 drive breaker bar
* 1/2 drive 32mm socket
* wrench for the tie rod nut (17 or 19mm?)
* tie rod separator tool (either a fork (which can damage the ball joint (be careful) or a tool that clamps to the control arm and a threaded bolt pushs the tie rod out (best tool)).
* small punch to knock the DOJ joint transmission outdrive pin out
* hammer (for the above punch)
* hub tamer or big puller to push axle out of hub (usually not required)
* replacement CV joint
* replacement axle nut (DO NOT REUSE the old one)
* replacement cotter pin for the ball joint nut
Step 1: spray the axle nut, tie rod nut and DOJ pin with penetrating oil once a day for a few days before the work is to be done.
Step 2: using the 32 mm socket and breaker pull remove the axle nut (this is difficult) (you should use a hardened impact wrench socket, I have seen regular ones shatter)
Step 3: remove the cotter pin and tie rod nut.
Step 4: using the tie rod removal tool, remove the ball joint from the lower control arm
Step 5: remove the pin from the inner CV joint.
Step 6: with the lower ball joint loose you should be able to pull the inner DOJ joint off the transmission outdrive.
Step 7: re install the ball joint temporarily
Step 8: use a hub tamer or big puller to push the CV axle out of the hub. Sometimes you can reinstall the axle nut loosely to protect the axle threads and hammer the axle gently loose. If using a hub tamer or puller the brake rotors and brake shield have to come off.
Step 9: pull the axle from the hub
Reverse for installation of new axle.
While you are at it I suggest the following work (since at 190,000 km you are likely due for it):
replace front wheel bearings (or if recently done, replace the inner bearing seals (they seal against the CV joint)). If using new bearings you MUST clean and repack the new bearing with proper bearing grease, the clear grease that it is shipped with is unsuitable.
replace the ball joints (again if not recently done)
While this is a relitively easy job (at least I now find it to be), the first time you do it is usually quite gruesome when it comes to removing the axle nut and tie rod from the control arm.
Where in Canada are you? I know a few mechanics that work for a more reasonable cost in Montreal, Calgary and Vancouver.
The CV joint replacement work on Subaru's is similar to all front wheel drive cars, so it is unlikely that your corner mechanic can screw it up. It is the wheel bearings that can be difficult without the proper hub tamer or Subaru specific tool.

It's a real time saver! Unless you need to change the ball joints as suggested above

I assume you mean the two bolts that are on the back of the control arm going into the body of the car, and the one bolt that holds the front of the control arm to the crossmember.
If so that will also work, but these bolts can be difficult to remove (like the axle nut), but likely easier than popping that darn ball joint. I find that coating the ball joint "rod" in anti seize really helps future disassembly jobs. I also can change an axle without taking the tie rod off, just the ball joint.
Just use threadlock on these bolts and nuts when reassembling.
At 190,000 km the ball joints are gone unless replaced and the front wheel bearings are near or past the usual failing point. If this is the case, he might as well stick to the ball joint method, or leave it to a mechanic.

Just replaced my axles, and they are very good....they do rally cars as well as overseas work. If you get your axles there, ask them to include new roll pins and axle nuts....they normally don't include unless you ask.
I took the two bolts off for the struts......My alignment may be off slightly, but I scribed the spindle so it's very damn close to where it was.
I started doing the ball joint method and new it was going to be a major pain in the butt.

The fastest way to do it IMO is pop the balljoints out of the knuckle. There is absolutely no need to do anything with the tie-rod ends or swaybar links...
