    Best brand tires?

    One can usually read user reviews about the various brands-models of tires at places like Tire Rack, or DiscountTireDirect. Always best to research various tires before plucking down cash. One hopefully wishes to come away with not only good value for your money spent, but a tire that does...

    Best brand tires?

    If you are looking for an all season M&S Tire, I think you'd be hard pressed besting Michelin. Yes, usually one of your most expensive tires, but also commonly do all things very well, ride, handling, both wet and dry weather, and the mileage you'll get from them. Another, might be Nitto, they...

    99 tahoe leaking coolant...any ideas?

    Well yeah, any common sense motor should've had a nipple, instead of that stupid **** GM threw on the 5.7L. Way too much **** is built today, that you can't even change a freaking air filter, without paying the dealer. I truly believe, that in the future, instead of me buying any newer...

    99 tahoe leaking coolant...any ideas?

    If it's any help, and this is the actual cause of the leak, I basically had my 97's quick connect coupler begin to leak almost from day one of ownership brand new. After a few months of looking at that idiotic part leak, and wiping at that area, I decided to do something about it. Simply went...

    Ways to improve suspension

    Hi, With many of these vehicles, and at the age they are at, then everything underneath can become suspect. Worn parts, you name it. Check your truck by bouncing on the front and back, a simple test is that the truck should only rebound once, no more. Might even be wise to spend a few...

    Best sparkplugs?

    Back in the day when these trucks were made, I don't even think Iridium were on the scene yet, or were just starting to come onto the scene being available. I'd say if you're keeping the truck, don't skimp, but don't get fancy with Bosch plus 4's, or any other crap like that, go with the stock...

    1999 tahoe rear disc brake conversion, developed issue

    Sorry all, what I meant to say was "Hydroboost". Again, like I said, the OBS Master Cylinder was not designed for Rear Disc Brakes. And I believe an NBS (New Body Style) Master Cylinder will not button up to the Booster without some machining modification due to a difference in the...

    1999 tahoe rear disc brake conversion, developed issue

    I'm no expert on such, but you should probably go over to the Tahoe-Z71 Forum, and the boys there will tell you why such is most likely occurring. I'm thinking the reason you now see actual losses instead of gains, is because the Disc Calipers have much more brake fluid volume compared to the...

    A/C Not Engaging

    More than likely you have a refrigerant leak somewhere. All line fittings might look fine. A common culprit is the compressor itself. See any evidence of oil on the compressor housing?

    Is '95-'99 Rear Disc Brake conversion available?

    As I understand it from other's input from the the other Tahoe/Yukon/Z71 Forum, converting to disc brakes on the old body style will actually cause you to lose braking efficiency on the old body style Hoes/Kons, no matter how cool this upgrade may seem. They claim the reason is, is the Stock...

    Sad tahoe.

    Here's how mine looked after I was done. I stayed with the stock looking lights, as I was concerned of going with something non-stock, or projector style and then possibly having reduced light spread on the road at night. ( I do have the Hi-4 Kit, had this for a good number of years before...

    Sad tahoe.

    About a year ago, I replaced all my lights and lenses with aftermarket, and although my headlights were not this far off, when I put the Grill back on, the Headlight Assemblies did not look quite centered within the openings like the stock factory lights did. So, I made note of which...

    1999Tahoe 5.7 soft pedal brakes - solved

    No Doubt with vehicles that are our age, every rubber (and many plastic) parts begins to rot, harden, deteriorate. This is something I myself will probably, and should address in the next coming weeks, going through my Tahoe, inspecting, and at least treating all of the rubber, cables, hoses...

    Shocks recommendation for 98 Tahoe?

    That's something I did also on mine, a pair of Firestone Ride Rite Air Bags in the rear 10 full years ago on my '97, and they were a wise buy. When I moved here to NM, I easily had 700 lbs of weight in the back, plus 300 lbs of tongue weight from the Cargo Trailer in tow, and never knew it...

    1999Tahoe 5.7 soft pedal brakes - solved

    Now this is something I cannot quite understand here? :confused: As far as I know, your 99 Hoe uses the exact same power booster as my 97 does. And that there is only one vacuum line going to that booster, no more. That Vaccum Hose inserts into a right angle plastic check valve which...

    Shocks recommendation for 98 Tahoe?

    I've heard-read no to KYB, Rancho Shocks I've had on some past Pickups, like the Rancho 9000 I believe, and these were some real stiff hard riding shocks, will rattle your teeth out. And as for the Edelbrock IAS, I understand that shock is no more. Cheaper option and probably not bad at all...

    Shocks recommendation for 98 Tahoe?

    I've been quite happy with the yellow Bilstiens I put on the truck some years ago, no problems with them period. I believe they were the 4300 series? Mark

    Update on my brake issues 1997 Tahoe

    As we all basically know, our old OBS Tahoes had about the ****tiest brakes to ever come on a vehicle. Soft, spongy, and didn't stop worth a damn. So many have gone through meat grinders with brake issues on these older Hoes. The hot ticket, is supposedly the Hydroboost Conversion, but this...

    Update on my brake issues 1997 Tahoe

    It appeared that Sunlit and others on the other Tahoe forum seemed to claim that many leaked at the Resovoir, and MC Body. One would think this should be the "easy" part to get right, it's just two rubber washers-seals, right?

    Update on my brake issues 1997 Tahoe

    Thanks Lester! As a side, this man Sunlit Comet, who seems to be a very knowledgeable fella on the OBS Tahoes, had also advised me, if buying a rebuilt Booster, to stay away from some of the "house brands", like duralast, etc etc, and stick with either Cardone, Bendix, AC/Delco. Not sure what...
