Uncle Rob Turbo Yukon: We Decided To Use The STOCK Exhaust... Can You Still Hear Turbo Sounds?

Watch on YouTube

What happens here

The presenter moves on to address two other critical components for the Yukon XL's performance: the rear differential yoke seal and the oxygen (O2) sensors. He shows the newly acquired 'Yukon' adapter seal, which fits the billet yoke and resolves the earlier issue of an incompatible seal. He also presents new O2 sensors, explaining that the old ones were reading inaccurately, leading to poor engine tuning. Replacing them will allow for correct fuel trimming and improved drivability, especially after the turbocharger installation.

Goal: Replace the problematic rear differential yoke seal and inaccurate O2 sensors.

Tools and materials

  • New O2 Sensors — Replacing old, inaccurate O2 sensors for better engine tuning
  • Wrench Set — Removing and installing the yoke seal and O2 sensors
  • Yoke Seal Adapter Yukon — Adapting the billet yoke for a compatible seal

remember that uh yolk adapter i was telling you about well i got one from summit it is exactly what we needed there's the old original one there boom freaking money that'll work just great on the billet yoke which i left in the office i have to grab that i also got a couple new o2 sensors because the ones in there are old they're really really off apparently uh super tuner tanner found that out last time we were on the dyno so he said do me a favor put some new ones in there it'll start up idle and drive a lot better because of that because we can actually like make it right so we're gonna throw those in too making progress here also i got exhaust cutouts which i'm not putting those in tonight it'll be the same video but we're going to do that tomorrow uh i'll figure out where i'm put that too bottom line i'm pumped super pumped and logan cleaned the floor it looks freaking amazing hell yeah so for those of you who may want to do the same upgrade i just looked on the escalade to double check because this old dust shield outfit over there like that didn't fit on here because this shoulder was too big i thought hmm do i even have one on the escalade i looked under there i don't it is just this seal so press that seal on there you're good to go i guess if you really wanted to uh if you had a lathe you could put this on a lathe and machine this down and put a dust shield on it but you're taking material off really not a big deal we're not like off-road anyway so i don't think you really need it we're good to go let's throw this thing on
