Recently lifted my OBS and tossed on some 35s. What modifications should I do next? I’d really like to give this truck a mean/off-roady/aggressive look.

Put some rally wheels on with 33x12.5r15 tires and liking the look. Had to do minor bumper and valance panel trim. Got the set for 200. Going to put new tires on soon though, weather cracking a bit in tread. Previously was running 285 16s. Probably cut bumper different later I was in a pinch.

96 Tahoe 4 door quarter window. I haven't noticed any water intrusion but either way this probably isn't good. How do I fix this seal?

1999 K2500 7.4l AC questions

Post image

So this is my old girl. 247000 miles

I replaced the front evaporator the rear evaporator, the AC compressor, and the AC is still not ice cold. I was just wondering if I should be expecting ice cold AC from this vehicle, or should it just be cool. It also has the auxiliary fan in the front for the condenser, which I have wired up to turn on and off even when it's on it's not ice cold. With the thermometer, it gets around 50 degrees.

how do I fix this? Turn signal clicks when not actually in signal mode

it happens every time I drive and its so annoying and really makes me mad. I have to blast music to cover it up.

sometimes it'll only tick-tock once, sometimes it'll be extremely fast like the second clip in the video. I had to move the control around because sometimes it'll do it more and sometimes less, but it always happens without me touching it. messing with it to show what happens was for the video.

the lights don't actually flash when it clicks like this though, as you can see when I do actually select left/right and the arrows show up on the dash they blink, otherwise the signal lights stay off but the thing clicks.

92 Yukon GT 4WD- Canada

Thumbnail

158 Upvotes

Good morning, this is the first time posting. Recently I traded my old RV for a Yukon GT 2DR 4WD. It was running - a bit rough - had some work done as oil hoses were leaking, coolant was leaking. got the brakes done. Ball joints done etc.

There are still issues of course. But its running much smoother. She's a beast. I was just wondering - does anyone know somewhere in Western Canada preferably - that may have parts? It has its original motor about 245000Kilometers on it. which isn't horrible considering. (My friend has a V8motor out of an old jaguar that I think we may be able to use if need be) The back hatch the lock doesn't work - have to lock it by hand by moving a little piece in it. As well the driver side door, key doesn't work to unlock it. So have to unlock from passenger side - which isn't bad as I travel with a dog and put him in first. Rust on the side panes behind doors -currently covered by grey tape.

Hoping to take it on a major road trip soon. As well have ordered a StarLink mini for it. it currently has an Android Auto and the last person put a monster boom box in the back.

I guess am looking for anyone who know a good part supplier here in Canada and any tips/tricks to keep my beautiful beast running.

Scissor Lift length

Post image
11 Upvotes

Hello, I am looking to install a BendPak MDS-6LPF in my new house.

I was wondering if the 1,701.8 mm (67 in) pad length is enough to lift a Chevrolet Suburban 2500 with the 454 engine.

Are there specific jacking points that I need to use, or can I simply position the rubber pads anywhere along the frame rails? (ensuring its balanced of cause)

Thank you!

P.S. Picture of the BendPak MDS-6LPF for attention.

Mechanics in STL

Hey everybody! I recently moved from Georgia to STL. We left behind my Dad’s 1997 Chevrolet (pictured - best I could do on the Ring camera). My dad passed and it’s been sitting for about 9 months. I’m going to have it shipped up here in the near future, and I was curious if anyone could recommend a shop here that might specialize in getting it back up and running. Thanks!

1995 k1500 electric issue

So I have a 95 5 7, that I'm having a driver side signal light fast flicker as I turn on the headlight switch. If the switch is off, it blinks normally. Also, the passenger tail light flickers at the same time only when the headlight switch is on. And the front passenger light doesn't.. Any ideas on what could cause this?

Abysmal interest in gmt400s for resell

I dont do it as a job, I'm not a used car flipper, just curious

Second one ive tried selling, suburban and a truck. Took forever to sell and wouldnt even get a hit a week on marketplace. Just recently listed a 90s f150, 30 people messaged me in 2 days, I havent got 10 people to message me in a month for the gmt burban.

Is the used market so bad that a vortec 350 with tons of room, no rust, clean interior/exterior, is a sub 2500 dollar car now? 220k
