What did you do to your OBS GMT400 Tahoe/Yukon Today?

[95escahoe]

Installed SS brake lines from Classic Tube. Could have done it myself but I only had one day to do it so... $300 later its in. Saw a post on NBS MC and decided to do that too and i'm not impressed with the results. Will do hydro next summer. BTW the kit is nice however one of the pieces for the rear was the wrong one completely but re-bent it to make it work.

Also replaced the shifter cable after it being a little to tight for too long. Felt like I was going to bust another column shifter. Well the new cable is like night and day. I zip past D now and have to get used to the smoothness of it. Got it on Amazon for $46, not bad

Love that kit

Finally got the broken off exhaust studs out and re-tapped so I could get the headers put on. Couldn't believe how easily they just dropped right in. Only down side, the O2 sensor hole was on the wrong side, gonna see what I need to do about that.

Next is new plugs tonight and tomorrow the rest of the exhaust (dual 2.5",dual cat, dual super 44's with H-pipe).

Did you pull the motor out to get them broken studs out? I think I have 3 on driver side and 2 on pass side. I wouldn't mind changing these studs out before I put my new
Exhaust system.

Nope, did it right where it was at. Luckily it wasn't the back studs. I don't know if I could have gotten them without trying the weld method. That would be a last resort for me.

Anyway, the body lift helped to be able to do some of the work thru the wheel-well.

Lucky u .... I might nee
d to pull wheel wells off to get to the back ones. What steps did u take to drill them out.

Well, I was taking off the stock exhaust manifold off to install headers (knowing that two bolts were already broken). So the manifolds were completely out of the way. They were broken off just inside the hole, I got a center punch to mark the center, drilled out the hole with a 5/16 bit, then tapped it with a 3/8 NC threader (the original threading). If you do this, take your time, if you break that threader or drill bit off in that hole, well good luck. Drill straight and when threading, for every little clockwise turn go back counterclockwise, and back it all the way out to clear out metal chunks.

They were the front holes on each side so like you said, very lucky.

The passenger side was pretty simple, the driver side, an entirely different story. There is a stupid bracket that comes off of the P/S pump that attaches to the front 2 studs of the exhaust manifold. I just cut it off on mine and will fabricate a new bracket. It's lazy, but I just didn't feel like dealing with that headache.

If the threads are sticking out you can always weld a nut onto it and work it out with a wrench.

Thought I was gonna go to alternator shop this week but nope too busy. need to drive my 2dr abd see if the efans are gonna work if not gonna swap back

 

[Berserker]

Got the dual exhaust with H-pipe installed. Wow, what a difference. 2 Flowmaster Super 44's sound amazing.

Side Note: Not a lot of options for placement of the H-pipe on these short 2-doors but found a decent one.

nothing but let it get rained on

replaced the wiper motor on my 96 with a reman autozone unit. seems smooth as glass. these jobs make you love these trucks. took me all of a half hour and 52 bucks

 

[tahoe.mkIII]

busy weekend with the tahoe.replaced/installed:
-alternator with 145a delco 244
-water pump
-big 3
-belt
-all coolant/heater hoses & heater control valve
-coolant flush & tstat
-radiator with silla all aluminum rad($187ebay,welds are a bit ugly,but seem solid)
-pcm with 0411 from lextech
-electric '05 gmt800 fans
-erl and filter

did the pcm on friday night, took about 2 hours.started on first try.runs better, improved idle & throttle response.feels like it shifts smoother.highly recommend.the rest went smoothly, except the new tstat(delco) was defective.wasnt opening till 230*-240*.fans work great.truck is so quiet now.they switch on around 225*-230* which seems a bit high to me, ill have to ask lextech what they are programmed for...still have to make a few brackets for the fans and put on the new shroud.but very happy with the switch so far...

last weekend i replaced all of the steel brake lines, brake hoses, calipers, hawk pads, rotors, wheel cyl, drums & hardware.the brake line to the rear was a pain in the ass

a month or so ago i replaced the ac compressor, lines, condenser, accumulator & switches (with a good amount of assistance from SLC)

Put my new exhaust system on today.

 

[98blackbell]

Last weekend :

New brake pads
Replace the ball joints
New tires
New hinge pins
All new rubber seals
New weather tech mats front and in rear cargo
Cleaned it
Drove it to my son to use for the week 240 miles got 16.2 mph at 85mph
Picking it up in 3 days hooking the trailer up to it loading the kids 74 260z and on the way to ZNATIONALS. 550 miles.

Didn't realize how bad the doors were. Nice driving a quiet ride.

Question on install of the gasket on rear hatch will post in separate blog.

 

[Popeye]

Chasing a electrical (Park lights) gremlin for the last 2 days .... to be continued today too.

 

[noJeepshere]

Last week did the balljoints, and now I'm stumped on why the engine is stumbling when I get in the throttle. Cruising it's fine, but any hill or acceleration and it coughs and runs rough and is somewhat down on power. Fuel pump, fuel filter, cap and rotor, wires and plugs are all new in the last year or so. Air filter was just cleaned and maf sensor was cleaned last week. Beyond that I'm lost, I don't like trying to fix fuel injected motors, too complex.

cent frum a smaert fone

started the hoe....

was driving around in the silverado and had a mechanical failure...luckily i was just blocks from home

 

[I go every where]

Changed the oil, trans and transfercase fluid. And during an argument with the ol' lady, slammed the back glass and it shattered . Got the whole back hatch from the junk yard for $85 but I lost all my stickers.

Also, im thinking about not putting the wiper and motor back on because it doesnt work for shit any ways and I think it gives the back a smoother look. Anybody ever done this? Any creative ways to cover the 2 holes in the glass?
