    ball joint replacement

    No. No no no! The Harbor Freight balljoint tool is crap. I own one, and the C-clamp bent up the first time I used it, while installing a ball joint on my Yukon. No impact gun was used, just a long ratchet. In other words, I bent up their sorry excuse for a clamp with my bare hands. The...

    305/45/22 fitment question

    I run 305/40-22s on my 99 Yukon. Offset on my rims is 8 from what I can ascertain.. I bought them on Discount Tire Direct, and they're not sold anymore.. so I had to discern from other information sources. Right now I'm at stock height, but in the process of lowering 4 inches on the front. I...

    1999 Denali body panels?

    Hi all.. I've got a 99 Yukon, non-Denali.. and every time I see a 99 Denali, I wish I had those body panels that protect the truck from dings, just like the panels that go on the 2006 Escalades. Does anyone know what these panels are called, and where to get them? I've looked at LMC Truck...

    Body parts Anyone?!

    Google Chrome is blocking access to that site because Chrome thinks the site is hosting malware. FYI.

    Any OBS and NBS owners out there want to comment on reliability?

    Check it... I've got a 99 Yukon, and if I had one word to describe everything I know about GMT400s versus what you have, it would be: inadequate. The brakes are inadequate - severely lacking in the front and the back. Using a distributor and a central coil pack, is inadequate, and there's no...

    Common issues on 05/06 GMT800s?

    Another question.. Hydroboost. I've noticed that all the Escalades and Denalis in the 2005/2006 model years, seem to have Hydroboost. I also found it on a bastard Tahoe LS with the cloth interior. Any idea how many of these GMT800s in the 05/06 year are going to have Hydroboost? Is there any...

    Common issues on 05/06 GMT800s?

    It looks like GMT800s also suffer from issues with corroding brake and fuel lines, particularly in northern states. I live in the south and we don't see much snow, so I'm not so worried. Have any of you had to mess with brake/fuel lines on your GMT800?

    Common issues on 05/06 GMT800s?

    Hi all. I'm helping a friend shop for trucks, and we've settled on the 05-06 model years. I don't know whether it'll end up being a Tahoe, Yukon or Escalade. Personally I'm partial to a particular 06 Escalade that has the LQ9 (6.0) and hydroboost brakes. What are some of the common issues...

    NO SECURITY LIGHT and Tahoe WON'T start

    Your security light could've been disconnected or removed because it stayed on persistently. What was the viper box you removed? Are you sure it wasnt a bypass module for the Passlock/EVO box?

    Side Mirrors

    I'm also searching for a set of mirrors for my 99 Yukon. I've had bad luck so far ordering from ebay (every time I buy a set of non-OEMs, the order gets cancelled because there's no stock availability). I've also read that non-GM mirrors do vibrate alot like you said. I guess at this point...

    Need an idler arm

    Ahh but the plot thickens! You seem to be an absolute fountain of knowledge, kudos! I took your advice and looked at the Moog parts.. and right on the Rockauto website, they had a link to a guide by Moog on how to determine whether you have bad idler arms. It says specifically, not to use any...

    Need an idler arm

    Hi all. I went to get tires put on my 99 Yukon today, and had a problem pointed out to me with the passenger side idler arm. This would stand to reason, since I recall hitting the curb on the passenger side several times during downtown parallel parking maneuvers. Rather than having the shop...

    Replacing plugs - what kind should I get? And what gap?

    Thanks all. I'll be ordering plugs, wires, rotor and cap tomorrow. I've never done a distributor before, but have read through the procedure in Alldata. As I understand it, since I won't be changing the position of the gear, I'll just mark the firing position of the old rotor to the motor...

    Replacing plugs - what kind should I get? And what gap?

    Truck is a 99 Yukon. I'm seeing everything from platinum, to double platinum, to iridium. A large cross-section of people seem to like Delco plugs. Is Delco Iridium or Double-Platinum a good choice, or is there something better? Also I seem to recall seeing something about how the gap is...

    Paint shop in South FL?

    Hi all. I'm looking to strip my 99 Yukon to the bone and paint it with a new color. That means that in addition to removing bumpers, doors, all exterior trim, windows, etc., I also plan to gut the interior. That means everything - carpet, dash, seats, trim, all of it. I'm also capable of...

    All about injectors

    Interesting, i'll keep that in mind about the fuel pump if all else fails. Being 13 years old, I can easily see that it might be time. I've only felt the 'drop out' on the cruise control a handful of times, and on manual throttle once. It was so minor that it could've been anything really...

    All about injectors

    Thanks for the replies.. I'll definitely try going closer to 68 and see what happens. I've read that the stock setup seems to be most efficient right at 2k RPM on the highway, which falls into the 68 to 69 mph category if I remember correctly. Of course the ultimate would be if I could make it...

    All about injectors

    I've got a 99 Yukon.. I was told the engine was replaced 40k miles ago because the original owner ran it hot, but I don't know if that means a completely new crate engine or what. So how would I know if it has poppet injectors? Is there a part number or something I can look for around the...

    Going shopping for rims!

    I'm determined to cop some 22 inch rims while Black Friday / Cyber Monday sales are in effect. I've found a few decent rims on sale online for my 99 Yukon (which is 5-127 I believe). But before I commit to anything, I'd like to troll ebay/Craigslist to make sure I'm getting the most bang for...
