Well, while I'm waiting to find another 89-91 Si tranny *HINT - I'M IN NEED* I decided to fix some bad boots. The axels weren't clicking just yet, but the boots were blown to hell.

So first off, there's a ring clip on the inner(trannyside) cv joint. Once thats off, you can slide the axel bearings off.

So then pull the old boot off and clean the shaft. http://www.we-todd-did-racing....D.jpg

Slide the new boot on, if you're replacing both sides, make sure you do the outter(hub) side first. http://www.we-todd-did-racing....D.jpg

Heres' the inner shaft side with the new boot showing you what the axel end looks like. http://www.we-todd-did-racing....D.jpg

Then its grease time. I filled the shafts housing (part that actually goes into the transmission and then greased up the bearing. http://www.we-todd-did-racing....D.jpg

Then just slide it back together and clamp it. The clamps are kind of a bitch, I used some channel locks and a screwdriver to tighten it as much as possible, the tighter the better. If they're loose enough to leak, they're most likely to break again. Here's the afterwards pic, http://www.we-todd-did-racing....D.jpg

Well, I hope this helps somebody. This is well worth the labor since axels are about $65-70 dollars each. Also, remanufactured ones suck, and I like to get greasy . Any questions/comments post 'em. I posted here in tech so that some people can see this thread, and then maybe the mighty Vap can move it for me to the FAQ thread. - Darrell

 

yea most people think when the bood rips the axle is done however that is not the case

 

Yep, but taking the extra 20 mins to replace any broken boots is well worth it down the line. - Darrell
