1987 K5 Sierra Classic

[Mr Bear]

Scored this one owner. Great shape, 87k original miles. 5.7L

Bringing it up to daily driver reliability so just going through the standard checks and services.

So far, new radiator/thermostat/coolant temp sensor and temp sender.

Rebuilt the TBI with new injectors, 1/4" injector spacer, 14 lb spring and all new gaskets.

Tuned it with new cap, rotor, coil and plugs. Base timing was 10 atdc so reset it to 0/tdc with the dizzy unplugged.

Serviced the axles. Both are open diff, no locker. Front was a bit like coffee with cream but 4wd works and no worries. all the brakes are new.

Pretty much eliminated the steering problem. First and foremost, removed the ridiculous oversized 32x11.50x15 Goodrich's and went back to stock size. Now the speedo is correct. Went through the suspension replacing worn tie rod ends, drag link and steering box. Swapped rag joint for borgeson extreme duty double u joint intermediate shaft. Aligned it and added extra 1/8" toe. Still want to replace the front springs and shackles and sway bar mounts but its a pleasure to drive now. Tramlining is all but eliminated.

It has new stainless dual exhaust with obnoxious magnaflow mufflers. They just have to come off soon. I can't hear myself think.

Future plans include servicing the transmission and transfer case and most likely ditching the hard top with its sliding windows for a soft top.
