Hello, I’m thinking about putting a six inch lift from superlift on my 1999 Chevrolet Silverado 1500 4wd, extended cab. My question today is what would be the recommended wheel size (both tire and rim) for this setup and I’d like it to preferably stick out on the side a bit but it’s not needed. I know many run 35” but again I’m not sure.

Hello guys & lady mechanics,
I’m in the process of replacing my rear disc brakes, it has 4Wheel anti loc disc brakes. I have the rear rotors with the interior surface for the parking brake shoes. I have new rear backing plates and hardware. But I noticed a little bit of a runout in the axles, I’m assuming it’s normal bearing wear. It has 175,000 miles on it. Plus the brake lines rusted and caused a pedal to the floor issue for me, so I replaced every single brake line with all new stainless steel lines, and new brake hoses. It has new rotors and pads upfront. What I’m trying to find out, since it’s a 14 Bolt GM differential in the rear, what exactly do I have???
1) Is it a 9 1/2 inch ring gear, 14 bolt rear end, or is it a 10 1/2 inch ring gear 14 bolt rear end? Where can I find this out. I need to order bearings and seals, and a pinion seal which is leaking.
which is my next question,
2) how do I determine what size my pinion seal is before I order one?
O’Reilly shows 8 options 🤣
3) Last question is, I’m assuming I’m going to have to pull the cover, remove the locking pin for the limited slip differential, and push the axle in, pull the retaining clip, and pull the entire axle out to get to the seals and bearings, correct?
My plan is to put a new B&M aluminum
differential cover and fresh fluid once this is all done…
Lastly I wish I would’ve found this side or search prior to doing my brakes, I would’ve found out that GM was offering half off To replace all new brake lines for $500. It’s done now though.
Happy holidays you’ll
I have a 1991 gmc sonoma with 4.3 and I recently replaced idler pully and no more then a mile after replacement my truck stalled out. Immediately after replacing pully truck idled weird for a moment so I shut off the engine and restarted the motor. I took it for a test ride around the block and it seemed to be driving great as soon as i pulled back up to the shop the engined stalled out and I could not restart the engine. It seems like my fuel is being delivered to throttle body as i have replaced fuel pump and i am still having the same problem. The fuel lines have gas at the throttle body and i can hear fuel pump turning on . if I spray staring fluid it will crank but then it dies. I dont know if it is bad injectors or if its something else. About2 weeks ago i installed a throttle body spacer not sure if that has anything to do with this but I drove the truck daily and it was only after the pully install that this issue began. Please help i miss my truck

Hello, for the past two years my truck (2015 Sierra 1500 All Terrain) has been intermittently flashing service lights saying the to service ABS, to service stabillitrac, and to service parking sensors. This would happen a few times a month and would immediately go away and I would think that it was just an annoying bug. But since about a month ago, when making low speed left turns, as well as any size bump, caused it to happen. This worsens into ABS light and stabillitrac light on for one day. While this happened you could feel the ABS pumping at when braking normally. This too went away the next day. I took the truck to the dealer for a diagnostic and told them all of this as well. After the $190 diagnosis they said it was the following codes (attached photo)
C0035-04, C0040-04, and C0035-0F.
they told me both front hubs were bad and needed replacement. They wanted $1800 for parts and labor. I told them thank you and paid the diagnosis and took the truck home. After the dealer the trucks electronics and 10x worse. Now the ABS and Stabillitrac lights stay on permanently, the brake light dings and flashes with any turn of the steering wheel. Also getting constant service ABS, service trailer brakes, Service stabillitrac, and reduced steering assist. I bought both front hubs and wheel speed sensors. I installed them and torqued everything back to spec. After reconnecting the battery and taking a test drive nothing had changed. I took the top panel from the dash off and did the ground mods. Again, no change. I’m going crazy trying to find the problem. I the. Took the truck to autozone for a code read. It still says the same three codes and it did, even after replacing the parts and sensors the dealer said would work. If anyone knows what the cause is it would be much appreciated. Thanks in advance, Dave
