Ok, I need some help.
Does anyone know the torque settings for the ball joints on the drag link that goes from front tire to front tire? I looked in the service manual and I THINK its 50 ft-lbs, then turn to the next cotter pin hole, but I can't tell for sure. The book doesn't call it a drag link or center link and only refers to a tie rod - which I think is the rod that goes from the pitman arm to the steering arm. I also looked in the assembly guide - - no dice. Heres a pic from the assembly guide of the ball joint I am speaking of.......thanks guys. |

Tie rod is what goes from steering knuckle....... to steering knuckle...drag link connects pitman arm to steering arm....what you are referring to is the "tie rod end"
I have a torque chart somewhere if I can find it. from LMC catalog: Attachment 1635701 |

There's no need for factory specs because the size of the bolt and it's grade will determine what's needed for the proper torque. I have this chart posted on the shop wall.

Attempting some progress this weekend - but as always, hit some snags.
I was reviewing some build threads looking at steering dampers and stumbled across this pic on Big J's build of a front parking brake cable support. See pic from his build below. I have the two smaller rear ones that are about 3 - 4 inches long, but I don't have a longer one for the front passenger side. That one looks 14 to 16 inches long. One, am I supposed to have it (assume answer is yes) on a 1972 and two, any ideas on a source? Not shocked I don't have it as the the PO's work included taking the rear drums parking brake lever out from between the shoes, so clearly it didn't have a functioning parking brake..... |
Re: 1972 Blazer CST Frame off Project in NC
Yes supposed to have one. A wtb on the parts board should turn up. I'll look here to see if I have one to spare.

Had a good weekend - got almost everything off the to do list for the weekend.
DONE: ** Rear brakes completed, including having to fabricate an adjuster opening in the brake backer plate. I don't think I've posted this before, but when I rebuilt the rear axles, I replaced the stock brake backer plates with an original set of heavy duty brake backer plates. This gives me a set of shoes that are 2 3/4" wide versus 2", so I gained about 30% of stopping power. I decided I wanted to keep rear drums for three reasons - 1) 70% of braking is in the front and with my new slotted rotors and dual caliper Wilwoods, that seemed sufficient. 2) Rear discs move you to a 16" wheel and I wanted to stay with 15" - that backfired when I had to move to 16" wheels due to front clearance. And, 3) Rear discs cost almost triple what this cost me. ** Tie rod cleaned, POR-15'd, tie rod ends installed and mounted ** Fuel tank modified (swapped filler neck from old tank to new tank), repainted - and POR-15'd the straps. Would've mounted it too if I'd had four arms - - or a helper. NOT DONE: ** Steering damper not installed. I bought a Monroe shock and had some clearance issues - plus I just didn't like the Monroe shock. I am going to try a Bilstein. Now, some pics.......and A ROLLING CHASIS! |

Looking great Chris. Congrats on getting her rolling! That parking brake cable support looks easy enough to make yourself if you don't come across one.

Re: 1972 Blazer CST Frame off Project in NC
Hey guys - - I am curious if anyone has any advice on what to complete BEFORE putting the tub back on the body. My body guy texted and he is in the final stages - exciting and scary!
So far, here is what I have done: * Run all brake and fuel lines * Installed leaf springs, axles and shocks * Installed engine and trans crossmembers * Front and Rear brakes * Wheels and tires * Parking Brake installed Still left to do (at least in my mind): * Fuel tank, sending unit and rubber fuel lines * Transfer Case and Trans installed * Drive shafts installed Then put the tub on Not sure if there is anything else - tail light wires, etc - but all that seems like it would be easy post tub install. Appreciate any suggestions from guys that have been there, done that. Thanks! |

And had an interesting find last week. I was looking at torque converters and discovered a guy here in Cornelius who builds them for racers all over the world. One man shop, super knowledgeable and professional. He is building mine for me and I should have it next week. The beauty of a local guy is service after the sale - he said if I was in any way unhappy with its stall limit (after I get everything back together), he'd adjust it for me for free. Hard to beat. |
Re: 1972 Blazer CST Frame off Project in NC
If they are done, I would install the engine, trans, and transfer case, before the tub.

I did tackle the Transfer Case - and got it mostly installed. I ran into a problem with the bolts for the side of the transfer case that connects it to the frame - the 3 piece stabilizer with the rubber bushings. I tried to reinstall the bolts from the PO and they would get tight, then slip the thread and be loose again. So, I went and got new bolts - 9/16-12 and it still felt loose in the thread. Tried to torque it up and same thing - - once it got past snug, it slipped the thread. So I thought I have the wrong bolt for sure. Bought a 5/8-11 but couldn't get it started. Also picked up some M14 (too small and slid right into the hole) and M16 (wouldn't thread, like the 5/8), and neither worked. So, I am guessing the 9/16-12 is the right bolt and pitch, but thats not fixing my slipping problem. Anyone got a recommendation on a fix - - or a confirmation on bolt size? I know alot of guys run without this brace, but I want it on there. Thanks - - kinda stuck |
Re: 1972 Blazer CST Frame off Project in NC
I am guessing you are sure the threads are not stripped.

The silver lining is it's fixed now and I met an awesome machinist in the process. A true craftsman. :metal: |
