Radius rod bushings?

[Curt]

What replacement radius rod bushings work on a 74 datsun 620? Are these correct? They are listed for the 620 ute. http://www.energysuspensionparts.com/proddetail.asp?prod=W81194

After inspection the front and rear bushings on the rod, they look the same.

I used sway bar bushings on the 521,cheaper and same size

Tension rod bushings are larger than the sway bar bushings I think. 

[Curt]

Is that what it is called? Tension rod. The bushings on the ends of the tension rod are wider and narrower than the swaybar bushings for sure. They look more like a cab mount bushing but smaller. The bushings in the link look somewhat similar, but they are different. Can the correct bushing be sourced? Or is it a make something work kind of situation.

I got mine off rock auto. $7

MOOG Part # K9218

[Curt]

Sweet! I can't find em on rock auto for who knows why. The part number came up on the ol Google though. I'll try those out. The others were a bit rich for my blood for a gamble. Thanks again!

FWIW, I got some for my 510 and if I remember correctly, they had the OEM part # stamped on them,   Moog part from Rockauto.

I wouldn't replace with poly bushings. Use rubber. Poly are very firm and almost rock hard and the tension rod must be able to swing up and down with the lower control arm movement. Poly will resist this and the tension rod is forced to bend causing metal fatigue and failure. As the tension rod forms one side of a structurally strong triangle, it's failure could be catastrophic while driving.

[Curt]

Have any idea where I can find rubber bushings that will work? Having them be soft sounds right. As they age and get harder you can hear the rod creak against the metal especially when it is cold. The last thing I want is a failure, I do drive this thing almost everyday.

What about these? They looks similar. http://www.summitracing.com/parts/mog-k7040/overview/

Tension rod is also called radius rod, compression rod, strut rod, caster/castor rod or reaction rod. Datsun calls it " FRONT SUSPENSION TENSION ROD".

[Curt]

Can anyone verify that the bushings for a 78-79 620 are the same used in the 1974 620? Did they change the rods at all when they went to disk brake? I found a source for 78-79 radius rod bushings and I'm hoping they are interchangeable.

[ggzilla]

They are different. The front suspension was redesigned for the 1978 model year (July 1977) and uses the smaller Datsun 1200 units.

 

1972-1977 4 per side needed

56112-W5000 BUSH-RUBBER, TENSION ROD $3.50

 

Nissan sells them.

[Curt]

Awesome! Thanks again.
