    Need advice on prepping my Yukon's oil pan gasket

    I'm prepping for the reinstall of my oil pan this weekend. I have a few questions though: 1. What are the torque specs of the different oil pan bolts? I've seen different numbers online for different LS engines. Does my aluminum block "L92" engine spec out differently than its iron block...

    Need advice on prepping my Yukon's oil pan gasket

    Thanks for recommendation. I'm going now to look at sealants.

    Need advice on prepping my Yukon's oil pan gasket

    I'll do as you and apply the RTV in all 4 corners. The Felpro gasket seems better engineered than the OEM rivoted one. As far as dropping the steering rack, yes. My wife helped hold the steering rack just low enough so I could jimmy out the pan. The biggest test now is getting the front...

    Need advice on prepping my Yukon's oil pan gasket

    My NNBS Yukon XL Denali beat me up while I was removing the oil pan. Much more involved than I had expected. Have a bloody eye to prove it. So I'm in intermission mode, cleaning the pan and engine mounting surface. The replacement gasket I purchased is a Felpro Part#: 30693R. I has an...

    Trying to stiffen up rear axle movement

    All done. The sway bar is parallel to the floor and frame. Took it for a test drive. My rear feels like it can corner now. The difference is very noticeable on sharp turns. Cant wait to see how it performs at expressway speeds with the trailer. I'm wondering if I should upgrade the front...

    Trying to stiffen up rear axle movement

    Thanks. The instructions werent' very helpful. I'll have to raise the truck in the morning as I have a few more inches on the end links that I can shorten. Diagrams in the kit were confusing and there are washers, nuts, and bolts left over. Don't know if these are for spacers that...

    Trying to stiffen up rear axle movement

    Ok. I just finished installation of a Hellwig sway bar and end links for my Yukon XL Denali. Cornering seems better, rear feels more planted. I won't know how it really performs until it warms up some and I hitch up my travel trailer. What I did notice is that the bar hangs much lower than...

    Trying to stiffen up rear axle movement

    Do you know if a stiffer, solid Hellwig bar would result in more stability than the OEM hollow bar?

    Trying to stiffen up rear axle movement

    It was suggested by someone I know to upgrade the rear stabilizer bar on my 08 Yukon XL Denali to something aftermarket (ie larger/beefier). I do tow a 6000 lb trailer so I'm looking for suggestions to help with mitigate any rear end movement. I've read Eibach and Hellwig have products that...

    Tow/haul mode with my 6 speed Yukon Denali

    My trans temps when not towing are around 150 degrees. This summer will be the litmus test for my truck. In fact, I'm almost ready to pull the trigger on a tune with Black Bear as I've heard it really wakes up the 6.2 beast. Black Bear tuners are coming to my state in 3 weeks and I'm trying...

    Tow/haul mode with my 6 speed Yukon Denali

    I did this late last year in anticipation of towing my current trailer. The 2nd aux cooler is in line with the factory cooler. So far, temps have not exceeded 180 degrees. Definitely good practice.

    Tow/haul mode with my 6 speed Yukon Denali

    Thanks for the info. Yeah, I think all of the GMT9XX's have the stock transmission temp gauge in the DIC. It's definitely a nice feature. As far as the tow/haul option, I'll assume best practice and use it when the truck demands it; but when cruising at hwy speeds, I'll turn it off and try...

    Tow/haul mode with my 6 speed Yukon Denali

    I'm relatively new to towing with my 2008 Yukon XL Denali and I had a question regarding towing my travel trailer. I know the purpose of the tow/haul option on the gear selector. When active, it changes shift points, stays in a lower gear longer, and downshifts quicker when slowing down...

    Need help with squating on a 2008 XL Denali's rear while towing

    Update, dealer found the wiring harness leading to the compressor shorting out each unit. They replaced the harness and all is good now. Wish I could just keep the 16 Yukon I was driving around all weekend and let them keep my 08. It towed my trailer nicely.

    Rear air shock boot shredded...

    I'm assuming the truck has gone through 2 sets of rear air shocks due to the failure of the autoride compressor. The trucks at the dealer now being serviced. Another thread discussing my on-going issues...
