Everything was sorted out a few days ago. It turns out everything was done only a few days after it arrived and some miscommunication on my friends part ended up costing me some extra time. Jon promptly replied to my e-mail and was even cool enough to call me up and explain everything that I needed to know about my new rear diff. I can't wait to see what it can do, thanks Jon

 

Have had many interactions with Jon, not even close to being as difficult as some describe. Wouldn't deal with anyone else

Like he said - one man operation, not some newbie cutting his or her teeth on my gears!!!

 

+1 Jon is a very friendly and knowledgable guy to talk with and I trust his work and attention to detail. In fact, I had a nice 45 minute conversation with him yesterday afternoon. My rear diff and trans are getting shipped out to him for complete build/upgrades in 2 weeks to support my new 2.4L build.

 

He does great work... been running his tranny/Xfer for years. However, his greatest attribute is his greatest downfall. He WILL spend 45mins (or MUCH more) on the phone with a customer explaining A to Z. That makes it hard for others to get a word in edgewise. I need to find the time/down time to send him my rear diff to make my TRE drivetrain complete.

 

i got my rear diff back from Jon at TRE a couple days ago and am very anxious to try it out,as far as downtime goes i could see where it might get frustrating for a guy that dd his car but when i opened the box i thought he made a mistake,****in thing looks brand new with the sight hole and all,awesome job!i thought he sent me someone elses diff lol,anyone know how the max lock diff would work with a gsc 40/60 center diff?my turn around was between 3-4 weeks which i thought was fine considering they send you the box then you send it back with your diff,they do the work and resend it back to you,i would recommend the service to anyone

 

+1 experienced first hand.

Yikes. A few years back mine took a week to turn around.

Seems to be a tad contraditory, but naturally the later information is better.

I'm going to hit 500 miles this Saturday, at which point, I"ll change the oil and go for a drive in the mountains for some more fun break-in time.

Question: how easy should I take it during that second 500 miles? 75% load/throttle OK? I'm not talking about clutch dumps or drag racing, I never do them anyway, but canyon carving, perhaps a little drift here and there. Should I continue to heat cycle, taking regular cool-down stops? Should I create a schedule interpolated between the very specific 0 to 100 mile instructions and an assumption of no limitations at 2000 miles?

I've searched for this discussion for an hour and not found it at this site, which surprizes me.

Opinions? Help me out here. It's hard to drive these cars like grandma so I'm trying to be careful but not over do it.

 

Here's the ridiculous schedule I came up with:

For Max Max Cool Max
Mile Speed Distance Down Load
100 60 20 30 10%
200 70 60 25 15.0%
300 75 100 20 20.0%
400 80 140 15 25.0%
500 86 180 12 30.0%
600 92 220 10 35.0%
700 98 260 8 40.0%
800 104 300 6 45.0%
900 110 340 5 50.0%
1000 116 380 4 55.0%
1100 122 420 3 60.0%
1200 128 460 3 65.0%
1300 134 500 2 70.0%
1400 140 540 2 75.0%
1500 146 580 1 80.0%
1600 152 620 1 85.0%
1700 158 660 1 90.0%
1800 164 700 1 95.0%
1900 170 740 1 100.0%

feel free to mock.

 

I would move the 1000 mile mark to 500 miles, and keep it out of boost below 500, and call it good after 1,000 miles. That's what I did since I pulled the inspection cover off the tcase and found an already pretty well developed wear pattern on the ring gear. I have since put almost another 1,000 miles on it, so it's going to get another fluid change this weekend and I'll take a look at the tcase gears again..

 

That's a good point. It should be a progressive change, not a linear one.

 

Anyone else had to wait a ridiculously long time for a core charge refund while having multiple emails ignored?

 

I didn't do a core exchange. Try calling him. He's answerd the last few times I have called.

 

Yeah Jon is pretty old school - phone is better than email.

 

He's hit or miss on both lol. Sometimes you wont get an email response after a few tries, then he'll call a week after your last email. Some times you get an email back. And sometimes you call and he answers. His voicemail is always full, so I've never left a message if he doesn't pick up..

 

I've had better luck with emails.

this is starting to ****ing **** me off.
