    Rear differential at 13.6k miles?

    BTW, I'll add that as nasty as my spider gears looked (pic below for reference), I didn't hear a peep out of my diff in the ~3k miles that I've owned the car. Finding this damage was a complete surprise to me...

    view from a different vantage point

    I agree! These are rare cars and I see another one on the road *maybe* once a year. Definitely a thrill each time...

    Oil and cooler line change

    A couple comments / warnings: These are for a Ram truck, so if you're going to make your own, don't follow these directly. Also, I went this route and really struggled to get them to not leak oil, even with brand new fittings. As someone who's been there / done that, I'd really advise you...

    My DIY differential gear change

    Got it. 50 ft-lbs is too tight; 200 is too loose. :) Seriously, Allan, thank you for all your input, feedback, and suggestions. It's truly helpful and this is the type of expertise I was hoping to tap into when I decided to share this process with this forum. Here's everything, clean...

    My DIY differential gear change

    Yup, I know that I'm stretching it here in attempting this myself. I expect to spend a good deal of time on my step 2) above, I have a tube of Prussian blue and I know where to get more... :)

    My DIY differential gear change

    Thanks for the heads up on this apparently joyful process. :) BTW, here's what I'm planning to do: 1) Install the pinion w/o the seal or crush sleeve. Torque enough to seat the bearings (50 ft-lbs?) 2) Install the carrier and check backlash and the mesh pattern. Iterate on the 3 spacers...

    My DIY differential gear change

    Thanks! Yes, I, too, was surprised by the delta in pinion teeth between the old and the new. I bought an OEM gearset from VPA (Jerry was a huge help!) Here are the ratios. Old: 14/43 = 3.0714 New: 11/39 = 3.5454

    My DIY differential gear change

    Thanks, Allan! Great to know the backlash setting range, and that you tend toward the tighter side. BTW, here are the torque settings I have so far. I never was successful in finding a service manual specifically for this unit, which I believe is a Super 44 / or Dana 226. However, I did find...

    Nicest License Plate Frame?

    Wow! Very nice. You should sell 'em... :)

    My DIY differential gear change

    One more tool needed that I made last night -- this one is a flange holder, needed to hold the pinion from turning while you're torquing on the nut. Here's what I came up with: The first version of this tool just had a 3/4" pipe screwed into a cast iron coupler, and in the first...

    Nicest License Plate Frame?

    +1. The MGW frame and the optional mounting hardware are just plain nice! Btw, I'm sure you already know that most aftermarket frames won't fit on these cars due to the limited vertical space - just something to bear in mind... Bryan

    My DIY differential gear change

    Okay, I could use a little help figuring out what I'm looking at on the ends of the pinions. Here's the old one: And here's the new one: I expected to see a number showing how far off (plus or minus) the ideal running position of the pinion gear is. On the new one, I think I see...

    My DIY differential gear change

    Thanks, Paul. I'll definitely try to cover the setup process during reassembly. The correct pinion depth + ring gear position = a good mesh pattern, plus how to set bearing preload. I already bought 2 quarts of the OEM fluid plus the friction modifier, but now Devin informs me that the...

    My DIY differential gear change

    I was able to get some more disassembly work done this morning. But before I went too far, I wanted to take some measurements of the existing setup. First is backlash. I had this dial indicator set from Grizzly: And set it up as such: Obviously the magnetic base didn't do any good on an...

    My DIY differential gear change

    Thanks! He convinced me that the Wavetrak is the best bang for the buck at this point. It's not cheap, but it comes with the output shafts, a lifetime warranty, and he likes the way it is "always operating", versus some other units where you have to induce wheel spin before they start doing...

    My DIY differential gear change

    WOW! Just spent an awesome 15 minutes on the phone with Devin. He's clearly the man when it comes to this stuff, so thank you Mark for the direction to him!!! New Wavetrak and bearing/seal kit on their way to me now... :D

    My DIY differential gear change

    Thanks, Mark. I think what I'm trying to figure out is what are my choices for aftermarket. At the low-end, an OEM take-out, as you suggested At the high-end, racing units like Quaife, Wavetrac, etc. Anything in-between? For example, are there replacement gears that go into the stock...

    My DIY differential gear change

    Thanks, Mark, I'll give them a call today. I think you're suggesting I put an OEM differential back in, so I'll ask this: Is every set of Gen3 spider gears destined to fail like this, or did I get a bad batch, or was this diff somehow abused at some point? My car has 30k miles, and while I...

    Good tips, Sonoman! I'll work those into the final write-up... Thanks!

    My DIY differential gear change

    Okay, I made a bit more progress tonight. And found some not good news... First thing was to build some type of fixture so I could work on this thing. I've seen the blue commercial ones but couldn't find where to buy one, so I made my own: It's a few pieces of flat bar stock welded...

    My DIY differential gear change

    I am going to attempt to document my DIY differential gear change project. Like many, I intend to swap out the stock 3.07:1 (too-tall) gearing in my 2005 Roadster for some 3.55 gears. From what I gather, not many choose to do all this work themselves, but my love for wrenching and learning new...

    Best 2005 Skip Shift Eliminator? Where to buy?

    FWIW, I put the skip-shift kit in and it did not eliminate the light. However, it doesn't bug me; now I just sort of laugh at it when it comes on and feel happy that I can still hit 2nd whenever I like... : ) Bryan

    ??? for anybody that can help me, cooling issues>>>>

    I know it's not optimal, but I did my own "flush" by draining the system, including the engine block, refilling with pure distilled water, running it until warm, re-draining, and then filling up again with the orange coolant (not pre-diluted) / distilled water mix. For the 2nd drain cycle, I...

    ??? for anybody that can help me, cooling issues>>>>

    How long has it been since the system was flushed? If it's the original coolant in there, a flush and fresh fluid is probably a great idea...

    Quick Release Battery Panel Cover with Mounted Connector for Battery Tender

    Agreed, mine stays nicely topped up just tapped into the 12V outlet in the console... But this panel is great for battery access, as many have noted!
