1970 Outer Tie Rod End
 

I am replacing the outer tie rod end passenger side on my 70 C10. This truck does have front disk brakes. I purchased the a Moog outer tie rod for it. Whenever I got the old one off it does not match the new one. The OD on the old one is larger than the new one. We went back to the parts store and looked at all tie rod ends thru 1987 and nothing matched. Thread on the old one is 1/2 20. Any ideas?

Re: 1970 Outer Tie Rod End
 

63-70 are one size, 71/72 are yet another size and 73-87 are yet another size. If yours are larger than your 70's then I would suspect you have a 73-87 spindle on there, just because 71/72 aren't prevalent and I would think you would know it. 73-87 tie rods have the largest threaded end.

Good luck!

Re: 1970 Outer Tie Rod End
 

63-70 OUTER tie rods are 5/8" LH thread.

71-72 OUTER tie rods are 11/16" RH thread.
73-87 OUTER tie rods are 11/16" RH thread.

Someone has changed parts in your front end.
Pics would help.
The tie rod has to match the spindle year.

Re: 1970 Outer Tie Rod End
 

I figured the previous owner used 73-87 parts for the conversion. But the length of the tie rod and size of the thread match none of these. I bought everything for a 70 outer, inner and sleeve to see if this will work.

Re: 1970 Outer Tie Rod End
 

1970 outer, inner and sleeve will work with a 63-70 center link and drum brake spindle.
The only way they will work with a disc brake spindle is if someone used aftermarket 63-70 disc brake conversion spindles.

You have to figure out what year spindle is on your truck!

Re: 1970 Outer Tie Rod End
 

Bottom tie rod is the one off the truck. The new tie rod is for a 70.

Re: 1970 Outer Tie Rod End
 

Is it possible that it's from a larger truck, 3/4 or 1 ton? I don't know but if the OP knows it's a 73-87 conversion then maybe it's a possibility?

I am not sure what this is off of.

Re: 1970 Outer Tie Rod End
 

Sorry, I misread your other post. Thought you said you figured out, not just figured. Pictures will be the only way to tell what crossmember and spindle you have.

Re: 1970 Outer Tie Rod End
 

The one off your truck is either a 71-72 tie rod or a 73-87 tie rod.
Inners, outers, sleeve, centerlink, and spindles all have to match.

How about some pics of your suspension under the truck?

Re: 1970 Outer Tie Rod End
 

i will snap some pics of the suspension. The 71-72 was alot longer than the one off the truck.

Steel a-arm bushings or rubber a-arm bushings?

Re: 1970 Outer Tie Rod End
 

Rubber

Re: 1970 Outer Tie Rod End
 

rubber makes it at least a 73. If you can give me the measurements I can cross it and see what number it is.
I would need the length from the thread end to the center of the stud, usually the grease fitting is in the center, thread size, the small diameter of the taper and the large diameter of the taper.

Re: 1970 Outer Tie Rod End
 

Yep,... 73-87.
There's only one 1/2-ton outer tie rod that I know of.

2WD versus 4WD?

Re: 1970 Outer Tie Rod End
 

2wd

Re: 1970 Outer Tie Rod End
 

Sorry, I meant your swap parts. I looked up C10-C30 and it was all the same part#. When I got to C50-70 it was different and the 4WD stuff was different as well. Taking measurements for Dave will hopefully get you what you need.

Re: 1970 Outer Tie Rod End
 

Here are the measurements I came up with using a mic.
Top of Taper-0.6310
Bottom of Taper-0.509
The threads mic at .65
Length to center of stud 6 1/4

Re: 1970 Outer Tie Rod End
 

Are the taper measurements on the taper? not on the threads or the straight part at the bottom 509 and 631 don't match to anything that's 6.25 long or +/- .50"

Threads are 5/8

Re: 1970 Outer Tie Rod End
 

I did find a ES678 6.62 long, 5/8-18 with 0.516 top 0.627 bottom taper for a 63-64 C10 it has a right hand thread and its an inner.

RS323L and RS323R are the outers but only 4" long with the same taper and threads. all for 63-64 possibly the tie-rods are flipped end for end?

Re: 1970 Outer Tie Rod End
 

I think the previous owner just used what he could find and did not use the correct parts.
