This chapter focuses on screw threads and their conventional representations.

This assumes that your truck was in perfect alignment before the repair which it probably wasn't because there were worn front end parts. Theoretically reassembling the tie rods with the exact turns should get you back to the same alignment you had before the repair. Tighten the bolt to 70 ft lbs install a new cotter pin and tighten the 2 clamps.Īt this point you should perform a 4 wheel alignment. Once the tie rod end gets drawn toward the steering arm cover I used a small jack to raise the tie rod end up so I could continue screwing it until the bolt dropped into the hole. Then put antisieze on the bushing threads and screw the sleeve onto the bushing while holding the tie rod end stable so it screws into the sleeve at the same time. Make sure you put the two clamps down over the sleeve. I cleaned up the sleeve, put antisieze on the inside threads and started the tie rod end. Small Jack to lift up the tie rod Photo by Chuck Kopelson As long as you have one left hand thread and one right hand thread per assembly it doesn't really matter how they go on so verify the part when ordering a replacement.
The left hand thread tie rod was originally installed on the outer end with the right hand on the inner side. The latest sleeves have a groove at each end to hold the clamps in the proper position. When you buy a new complete tie rodĪssembly you get a shorter adjusting sleeve or center section. You can freely mix and match these without a problem. These came out because the older straight joints bound up under extreme suspension flex.ĪMG calls the new design 'Zero Toe'. The tie rod shown is a newer design with an offset. The tie rods have a 7/8-18 bolt/pitch with a 5/8" center The tie rod end part 6011887 is a Right Hand thread. One has left hand threads, the other right.
The front upper and lower tie rod ends are threaded differently. Here's what brand new tie rod ends looks like.
