Question for those of you with yukons (non xl) that got the Escalade roof racks. Do any of you know the length from bolt holes to bolt holes?
I found a set locally but the guy can't remember if they came of an ext or regular Escalade but he has the measurements. Id compare it to my truck but my friend is looking at then for me because I'm at the hospital now with my wife and newborn daughter :)
Not bolt hole to bolt hole but the overall length is approximately 70 1/2” so if he takes the end caps and the center piece and lay them together it should be close to that. Or you could use the base gasket pieces. The XL’s would have to be 6” or so longer all together. Now get back to that baby sheesh!

How about measuring one of the rails...!? [emoji3166]

I just measured the bottom of one rail (same length as the middle-bottom plastic gasket underneath the rail), and it’s 51”


That should be your length. [emoji106][emoji631]

Sounds like his is from the longbody.

Thanks guys. He said from middle hole to middle hole was about 50".

Inner most holes, length was 50"

We can’t measure the holes without taking them apart, that’s why we are giving you outside dimensions. I’m not going to disassemble mine to find the mounting holes when he can measure the actual end to end of the whole thing or the length of the center section. Does that make more sense?

I'll see if I can get an end to end measurement

So, ever since I’ve owned the truck, I’ll periodically have “Service 4x4 System”, and odd behavior with the Transfer Case. It will randomly start
In Auto, when it was left in 2wd, and usually reset itself after a power off / on.. this morning, I started her up, and when I got in, she’s indicating 4lo... I was
pretty confident it wasn’t in 4lo, and as soon as I moved the vehicle, suspicion was confirmed.

However, driving the kiddo to school, I immediately noticed the transmission was shifting up way too early. I’d be going 15-20 through the neighborhood, and she’s in 4th gear, just crawling, and with a little vibration, I guess just because it was such a high gear for the speed. This definitely alarmed me.

So I manually shifted, and that worked fine. Got her home, got out the Tech2, and eventually was able to pull a C0327 code, which is for the decoder ring, and there’s a TSB for it. Ok, no biggie, I’ve been waiting for this. Got the replacement in, here’s the old one.. only pic I took:

So I’m glad about that. Only, I’m pretty concerned with how the trans was acting this morning... it seemed like once it warmed up, she shifted fine in drive, and I was able to shift 1,2,3 just fine before she warmed up. I’m guessing the tcase saying it was in 4lo caused the trans to shift oddly, since I was going well over any speed you’d be at in 4lo.. any thoughts on this..? I’m crossing my fingers that I don’t need to order that trans yet... but I do want to figure out exactly what I’m getting, and order soon, since it’s just a matter of time.

Oh, and I did install my new, genuine GM interior part today. Rough install...!

It was probably shifting like it was in lo range because that’s what it thought was going on so I would just monitor it. If it happens after you fix the other problem, that’s the time to worry. I used to have a decoder ring when I was a kid...:rolleyes:
