I have a 2017 LT 5.3 Z71 that just turned over 10k miles. I've never had a truck under warranty so I haven't jumped into many mods yet (did an intake tube and hoping for an exhaust soon though).
Trucks/jeeps I've had in the past I've upgraded the transmission pan to hold more fluid/cool better, on my Tahoe I did the same to the rear differential cover for toughness and cooling ability. I've never had a new truck but plan on holding onto it for a long time so my thoughts are longevity/preventative/bulletproofing the drivetrain.
Anyone have thoughts/experience/opinions?
I've seen several conflicting reports regarding the fluid capacities on both the front and rear differentials on my 07 Avalanche. The manual does a great job specifying the gear oil types but seems to be lacking the capacities part in the "fluids and capacities" section. Anyone have a good answer for me? I sure would appreciate it!
Hey all, I have a 1995 Sierra K3500 with a 14 bolt 10.5'' 4.10 30 spline rear, but it's not a posi and I'm looking to make it one the cheapest way possible. My father had a 1978 K30 with the exact same rear (14 bolt 10.5'' 4.10 30 spline) but with a posi. He ended up swapping it out with a open diff. Currently that posi unit is sitting at my Grandma's house in the shed and I'm wondering if I can use that. It is completely stock with the 4.10 still on it. So, I'm wondering if I could just take my current diff out of the cover and place the '78 unit in there no problem or is there more to it/not even possible? I'm not too familiar with rears so I'm not sure if the 17 year gap between the 2 trucks make a big difference in terms of rears.
I have a strange noise from my 200k 07 Burb diff. No howl, locker works fine. Only happens with foot on the gas and goes away when foot is off. Sounds like cats fighting in the rear diff or a rusty brake caliper inside. I listened with a stethoscope and it seems to be coming from the rear diff cover area, but hard to tell. Wheel bearings were quiet. U joints tight and quiet. The pinion is quiet and leak free. It's smooth on the road and the diff seems a little warm after a long drive. Fluid is clean and clear and there was some Very fine metallic dust covering the magnet. I have never heard anything like this. It's almost a scraping sound. Any ideas please let me know. Carrier bearings? Pinion shaft worn? Worn pinions? It's been a highway only vehicle and serviced regularly. I have a google video of it here: https://photos.app.goo.gl/hwgbHWYSxEZCRzrj2
