I need to replace the passenger half axle on our 95 impreza - the inner u-joint is getting really bad. From what I've heard, the best way to do this is just replace the whole axle. (correct me if I am wrong, though).
There are a lot of sources for half axles, including on ebay. I don't want to do this job more than once so what's a good source reliable source of rebuilds? I take it most places require a core?
This came up in a manual transmissions course (focused on all cars, not just Hondas) I took recently, and was treated at length. FWIW, generally speaking the preferred route, cost- and labor-wise, indeed is just to replace the entire half axle (a.k.a. "half shaft"). This came from the instructor and my own research on this, which showed that many automotive authors in the last few years recommend this route.
Napa and Autozone both offer lifetime warranties on half axles. The cost runs around $75, typically, at Napa and Autozone. This price does assume you return the core to Napa or Autozone or wherever. A junkyard may also sell rebuilt or used half axles, and for much less, like $5 (seriously) too. This was from reports from my classmates and the instructors.
OTOH, a quick groups.google turns up some folks who think Subarus axles should always be OEM and new. The boot rubber used by rebuilders such as Napa and Autozone etc. can be inferior.
Check the replacement half shaft diameter, length, and number of splines carefully with the old half shaft. That's one point that can trip up the person doing the repair. People say that when the match is not correct, Autozone etc. have no problem working with the customer to get the exact match.
The solution may depend on how much longer you want to keep this Subaru and so gamble on a rebuild through a place like Napa etc.
Yes. Furthermore, the Honda/Acura half shafts are said to be fairly easy to pull, too. Sounds like an intermediate level job (well, by my standards). It is something I would try on my own, especially since the young kids in my class who had pulled a half shaft said they typically had not found it too difficult. The easiness of the job to me argues for getting the ones with a lifetime warranty from Autozone or Napa. If I'd done the job at least once, I might even be able to talk myself into the cheaper ones from the local salvage yard.
IIRC, the variation in half shaft diameter, length, and spline number is somewhat notorious for Hondas, so measure all carefully at Autozone, etc.
Great - thanks! I'll try autozone. Have only messed with axles on my vw bug. Looking at the service manual it does not look difficult but seems involving.
I would get a dealer quote just for grins. Who knows, maybe their price is reasonable. Much depends on how long you plan to keep running the car. If you want another 11 years out of it, then a new Honda/Acura part might make sense. If another 2-5 years will do then a parts store rebuilt may be in order.
Thanks -- you're saying to replace that split ring, then?
About getting nuts off: I am restoring a vw beetle so after trying to get some of the rusted bolts off, I invested in an IR impact gun. If it doesn't come off, it will break :)
I recently did the timing belt on it. My wrench is 235 ft/lbs. Wouldn't budge the crankshaft pulley bolt. My brother had a 375 ft/lb IR. Ditto. A 5' pipe over the breaker bar did the trick on that. The impact wrench worked, but the pipe didn't on the Accord hub nut. I think the pipe was about 4' that time. The Civic nuts weren't as hub bad. I think you also have to separate the tie rod too. That was the only other obstacle. Good luck.
I've had success using a 235 ft-lb impact on axle nuts, but even the 500 ft-lb has to work at getting crankshaft bolts free.
I've also used a floor jack under a breaker bar to remove axle nuts when I didn't have air tools. It still helps to have a long breaker bar because the wheel always comes off the ground before the nut comes loose.
I was unclear - I apply torque to the breaker bar with the floor jack, as though I were really strong (yeah... right!) and lifting up on the breaker bar myself. The wheel always comes off the ground because I don't use a cheater bar, but the other front wheel has never cleared the ground. I've used a similar procedure on the crankshaft bolt of my old Volvo, but both front wheels came off the ground before the bolt loosened. There isn't room to do that with the crankshaft bolt of Hondas.
ok, i understand what you're describing, but with respect, i still don't get why. to my way of thinking, it's much easier to push down on a lever using gravity as your friend than it is to lift up against it. you can't lift a wheel off the ground that way [well, not unless you pivot the whole car against a truly locked bolt and succeed in lifting the other end] and i see no difference whether it's axle nuts or crankshaft pulley bolts. i'm a real lazy guy mike and i hate sweating to be the strong guy when i can just use the weight of my lardy rear end to assist my efforts. using a jack to lift a breaker bar is fraught with potential danger from what i can see.
The difference is that I only weigh about 200 lbs, while using the jack I can put much of the front half of the vehicle's weight to work... probably more than 1000 lbs. It's really quite safe. The wheel only comes up a few inches and the nut gives smoothly, lowering the car about like releasing the floor jack does. Think of it as jacking up that corner of the car by placing the jack under the breaker bar instead of the usual jack point. No sweat, no strain. Since you are standing on the far end of the jack you are well out of the way even if the socket pops off the nut.
In contrast, I once tried to loosen a crankshaft bolt with the trick of putting the breaker bar on a jackstand and bumping the starter (on a Toyota, not possible on most Hondas). It worked but was really spooky. The front end suddenly rose a few inches. I won't do that again.
First one leaked around the seal Second one ratcheted Third one leaked around the seal.
All had life time warranty and did these things right out of the shop.
I said the hell with it and had them put an OEM Honda axle.
Not a problem.
I'll stick with OEM from now on. The shop that replaced them was nice enough to not charge me a dime extra in labor for al that work. I'm they one that said use aftermarket. We both agreed in the end it wasn't worth it. I did pay the difference between the OEM and the Aftermarket axle.
Honda OEM, whether it's brake pads or exhaust or axles, work great. A Honda OEM exhaust is well worth the premium, for example. Anything else is a false economy if you're going to keep the car and actually use the part you bought.
