The R axle has different diff splines, that was the issue you had, correct? Quote Link to comment Share on other sites More sharing options...
BlackT5 Posted January 13, 2019 Report Share Posted January 13, 2019 I used a 99 angle gear. I had originally bought cheap axles from IPD, the passenger one they offered at the time had seal locations for either 2000 or 99 angle gears. Both of those axles split boots so I just replaced them with OEM 99R axles that I pulled from my parts car. The problem I had initially was on the driver side. I had just bought the passenger axle thinking the 2000R driver side would work but it was totally different Quote Link to comment Share on other sites More sharing options...

Side note, you could use a '00 AG in a '99, you'd just need the '00 right axle. Doesn't work the other way around (without additional mod), since the DP would be in the way.

I had just bought the passenger axle thinking the 2000R driver side would work but it was totally different I have OEM 99 axles that are in pretty good shape. I’d prefer to find a 99 angle gear so I can continue to use them instead of hunting for an axle to pair with my 00 R angle gear. I’ve had awful luck with aftermarket passenger axles, ran a few different brands with the same results - torn boot or excess play in less than 12 months from installing it. So, if anyone has a 99 angle gear they’re looking to sell, let me know! Quote Link to comment Share on other sites More sharing options...

I do, it's out of the car but still bolted to the engine/trans out in my garage so I'll have to remove to get a good pic of the splines.. was working fine though Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted January 16, 2019 Report Share Posted January 16, 2019 Pretty sure I still have a couple. I can check. Do you have the PN/ Casting # off yours for reference? Splines are good on mine. Quote Link to comment Share on other sites More sharing options...

andyb5 Posted March 3, 2019 Author Report Share Posted March 3, 2019 Yesterday I did an “autopsy” on the B5234T8 to 1) find the source of the knocking noise, and 2) find what could have caused the noise to occur. This was really fun and quite satisfying in the end. I didn’t take any pictures of the first couple steps but I stripped the remaining ancillary bits off, pulled the cylinder head, and removed the oil pan. After removing the oil pan, I found a failed o-ring at the connection between the oil pan and the crankcase. With close to 240,000 miles on the engine, I have no record of these o-rings being replaced. At this point I suspect the o-ring failure led to reduced oil pressure throughout the engine and insufficient lubrication to the bearings. Note that at no point prior to this engine being removed did the stock “oil pressure warning” instrument cluster light come on to alert me of a problem. Next, I started to remove the rods and pistons to examine the bearings and see what stories they had to share. As it turns out, they had quite a tale to tell! I’m about halfway through the process and remove the cap from rod #3 to find the bearing is spun 90 degrees around. That’s a sure sign that things have gone catastrophically wrong! This confirms my suspicions that it was rod-knock that I had been hearing a not an issue with the top end/valve train. I go to remove each half of the bearing and in doing so, I find an even more dramatic failure. One side of the bearing had fractured into 2 separate pieces! Now, I’m not a professional mechanic, but I can assume that’ll cause a few problems The crank journal on cyl 3 was gouged pretty deeply The intact half of the #3 rod bearing was worn down pretty dramatically - that surface should be silver, not copper. At least 1 full layer of metal had worn away from the bearing surface! This wear is caused by lack of oil supply and is how the big end of the rod has enough space to “knock” as it rotates around the crank. Cylinders 2 and 4 were showing signs of damage to the bearings as well. I suspect the both cylinders experienced low oil pressure, but not as low as cylinder 3 so they did not fail outright, but would have been an issue had this engine continued to be run/driven. Here’s a shot of my “coroner’s table” while I was working While I’m not happy that engine needed to be replaced, I am happy that I was proven correct in my initial diagnosis and it was fun to be able to take the time and really understand both how and why this engine failed so I can learn from this experience! 2 Quote Link to comment Share on other sites More sharing options...

Nope, it’ll get turned into a table. The head would probably be okay to reuse, I rebuilt it a few years ago but it’s a single VVT, hydro lifter RN head so it’s not really anything special or valuable.

Commander Riker Posted March 5, 2019 Report Share Posted March 5, 2019 Will be interested in a overall rebuild cost if you get one. Good luck with the rebuild. 🙂 Quote Link to comment Share on other sites More sharing options...
Zappo Posted March 5, 2019 Report Share Posted March 5, 2019 Yeah, I know that sound. Sounds like a rock in the valve train; worse as you rev it and quiet as it comes back down to idle. Salvage what you can for the next build! Quote Link to comment Share on other sites More sharing options...
Andzey Posted March 6, 2019 Report Share Posted March 6, 2019 I had a thread somewhere here on vs on my donor engine disassembly where conrod bearing was friction welded to the crank, I guess your engine would experience same after some time. The engine was extremely dirty, so I thought clogged crank oil passages caused oil starvation, but wooden oil pan o rings could be responsible as well Quote Link to comment Share on other sites More sharing options...
