Well, I think I have determined the culprit regarding the roaring noise coming from the engine above 60mph. I got looking on the drivers side, and noticed all the grease had been flung out of the inner cv boot. The boot itself looked ok, but when I crawled under the car, I noticed the axle could be wiggled up and down about 1/2 an inch where it goes into the transmission. It appears as if the boot was rubbing up against something and therefore lost it's grease. Is this a simple matter of replacing the driver's side axle? By the way, it is a 94 with a 3 speed auto.
After doing a little searching, I fear that the diffential in this car is toast. It sounds like maybe the fluid leaked out, and wore the gears to the point where the axle has lots of play where it goes into the differential. Does this sound right?? Won't know for sure till the weekend when I can check the fluid level.
Where is place where there is too much play? Is it where the axle enters the "tulip" joint (the big end of the metal cup near the differential ) or is it at the little end of the tulip joint where it goes into the differential. If the play is at the big end, it would be part of what gets replaced when you replace the half axle. If its at the little end then you have a problem inside the differential.
It's where it goes into the differential. I called the local tranny shop, and he said it's normal to have play where it goes into the diffential, is that a correct statement? He said that 1/2 inch play is ok.
In an out, or up and down perpendicular to the shaft play? In & out play is normal, the shsft is splined and just slides into the transaxle, retained by a spring clip inside. It can slide a bit before it hits the clip. But up & down, perpendicular to shaft play I don't think is good. I'd have to go outside & look at one of my trannys to see how much of that kind of play it has.
Yeah, this is up and down play, there isn't any front to back or side to side play. It's only about half an inch of movement, and it seems to be under some tension. According to the tranny shop, this is the movement of the differential gears I am feeling, but who knows. Let me know when you check yours, I'm curious if it is normal.
I checked out the spare transaxle I have, which is a manual 5sp C52, but the shafts should work similar. There is play, dunno about 1/2 inch, but I guess that depends on where you measure the play. The play is pretty even in all directions. Bad cv joint is quite possible. I've had a bad wheel bearing, that made quite a bit of noise.
hmmm...well Jmana that parts you need for the repair will be fairly affordable, but if you have to take it in, the labor will be costly. Do a little bit of research on parts and labor.....but again if you can do it yourself, you can save a ton of money and the experiences is rewarding!
True that. I'd rank CV assembly replacement as an intermediate level repair. It does require a few specialized tools. The one tool you cannot do it without is the large socket for the axle nut. I can do mine without undoing any parts on steering or hub, but thats because my CV shafts have the bolt on flange style at the transaxle side. Otherwise you'll need a ball joint tool or gear extractor for the steering. I find a slide hammer very useful for pulling the axle out of transaxle.
If you pull shaft out, you'll be able to feel if the bearing is trashed. At which point it's only a few bolts away from removing hub assembly. You can then buy the bearings, locally or online, take it to a shop and have them install the bearing, then put it in assembly yourself & get an alingment done.
You will want a torque wrench. These fastners you definitely want to torque to correct spec.
Easiest is to take the hub and take it to a shop that has both parts store and machine shop combined. They will R&R the Hub bearings.... it will save time and money. They wil also guarantee the work. Carquest has some stores that do this, Maybe Big A and Napa too,, but only at some of their stores.
I think I paid about $75.00 for new bearings and seals pressed in for a front hub.
