    Need some assistance with brakes...rears wore out in 50k miles

    Yet the fronts have almost no wear on them. I have noticed that the rears create alot of brake dust but I have never known the rears to wear out before the fronts. I have to change the pads tomorrow but what else should I be looking for? 03 Yukon, EBC pads front/rear with slotted rotors up front.

    Do the brakes need to be pre bled via scanner/tech II?

    I had to replace a ton of stuff on my brakes recently but still have a bit of a spongy feel. I heard that if air got into the master, that the dealer has to pre-bleed the master with a handheld, anyone ever have to do this?

    Finally upgraded my brakes!

    The stock shit sucked so bad it wasnt even funny! Everytime the brakes got wet, it would take over twice the distance to stop and the pads werent even worn halfway! Since upgrading everything on my Formula a few years back, I figured I would do the same thing to the Yukon. Discount tire direct...

    Anyone running withOUT catalytic converters?

    I got a P0420 code so its probably time(180k miles) to replace the cats, but rather than put new ones in I would rather use an off road pipe and tune out the rear o2's. What options are there for these things in terms of aftermarket ypipes?

    Anyone wire hids into the reverse lights?

    I got a set of H11's and got it all wired up but they wont both turn on at once. I picked up a wiring harness with a relay but no clue how to wire this thing. Anyone else try this on a NBS Yukon/Tahoe? When the one is lit up, its bright as fuck and is awesome for light but I really need em both...

    Reverse lights wont both light up after hid install...any ideas?

    Only 1 will light up at any time even though they both work. I swapped ballasts and bulbs and they work on either side but only 1 at a time, both wont light up for reverse. It worked once or twice but after that only 1. Anyone else have this issue?

    What rpm's does your 5.3l turn? I think my converter forgets to lock up.

    At 70mph, I am turning 2100rpms this just seems high to me. Even at 60mphs, its turning 2000rpms almost like its not in 4th gear even though it is. Whats the correct rpms for 60mphs? I thought it might be related to the cold and the converter not locking up properly but no matter how warm the...

    Will the motor from an 03' 5.3l work in a 99 Tahoe?

    I have my old motor for sale and someone wanted to know if he could use it to replace his popped 5.7l from a 99'. I know they will swap into the 4.8l with just an ecu but I dont know what all would be needed for it to work in a 99' 5.7l.

    Removed the roof rack and mudflaps, now I am done until Spring.

    After reading the thread about how to remove em, finally went outside and took em off. Very easy and imo looks much better and the damm mudflaps drove me nuts so that was an easy one. Only had it 2 months and so far the basic mods(cai, servo mod, full RP fluids, tuning, complete tune up...

    Boiling or bubbling sound from the front dash area....is this a heater core issue?

    Just noticed it lately and that the heat up front isnt that hot. Anyone ever have this symptom before? Would a core flush help with this?

    Noob questions about using auto 4wd vs 4x4....I dont have the owners manual.

    I have no idea when you are to use 4x4 or the auto4wd function. The last suv I had was a full-time awd Durango and before I owned all 2wd trucks. Crap weather is coming this way soon and I wanted to know the proper way to engage and use the 4wd functions. I had read that the auto function can do...

    Finally found the cause of my service 4wd error....

    Busted wheel bearing and stripped axle half shaft! The error code kept popping up on the dash and the switch kept flashing for the last few days then today it began to make an intermittent loud grinding noise. I ended up pulling the wheel, caliper and rotor off and began tugging on the bearing...

    Odd starting issues when cold/battery dying. Looking for ideas please..

    1.When its cold out, it takes a few cranks for the engine to turn over almost like it might not start but when warmed up it fires up fine. Could too small of a plug gap cause this now that its cold out? I had changed the gap a month back chasing down missfires. 2.So far this issue has happened...

    Where exactly is the stock amp in an 03 Yukon wiht Bose?

    I was thinking about bypassing the stock sub and using those leads for a line input on an amp/sub combo. I just need to know where the stock amp is so I can just work there. thanks!

    Got my HID foglights done!

    I got them from DDM tuning for only $40(yes, I know some have had issues but for the $$, was worth it)! It was very easy to do btw, all 30 minutes of it! I even took the lens cover off of the foglight and cut out the reflector so the bulb sat flush. this would be my lows(low 6 mod turned into...

    What kind of speakers/sizes come stock with the Bose cd/tape system?

    Anyone know if the speakers are 2 or 4ohm speakers and what sizes they are? The Monsoon stereos that come in the fbodies had 2 ohm speakers and could be replaced with a quality aftermarket speaker that sounded really good. So I am looking at something similar rather than gutting another vehicle.

    What Royal Purple fluid to run in front diff?

    I changed out the rear with the 75w90 but the front calls for 80w90 and the only one I could find was a 5 gallon jug. Can I use the same fluid for the front diff as the rear?
