Curt Posted April 25, 2014 Report Share Posted April 25, 2014 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. Quote Link to comment
kelowg Posted April 25, 2014 Report Share Posted April 25, 2014 I used sway bar bushings on the 521,cheaper and same size Quote Link to comment
datzenmike Posted April 25, 2014 Report Share Posted April 25, 2014 Tension rod bushings are larger than the sway bar bushings I think. Quote Link to comment
Curt Posted April 25, 2014 Author Report Share Posted April 25, 2014 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. Quote Link to comment
jvb5577 Posted April 26, 2014 Report Share Posted April 26, 2014 I got mine off rock auto. $7 MOOG Part # K9218 Quote Link to comment
Curt Posted April 26, 2014 Author Report Share Posted April 26, 2014 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! Quote Link to comment
KELMO Posted April 26, 2014 Report Share Posted April 26, 2014 FWIW, I got some for my 510 and if I remember correctly, they had the OEM part # stamped on them, Moog part from Rockauto. Quote Link to comment
datzenmike Posted April 26, 2014 Report Share Posted April 26, 2014 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. 1 Quote Link to comment
Curt Posted April 26, 2014 Author Report Share Posted April 26, 2014 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. Quote Link to comment
Curt Posted April 27, 2014 Author Report Share Posted April 27, 2014 What about these? They looks similar. http://www.summitracing.com/parts/mog-k7040/overview/ Quote Link to comment
ggzilla Posted April 27, 2014 Report Share Posted April 27, 2014 Tension rod is also called radius rod, compression rod, strut rod, caster/castor rod or reaction rod. Datsun calls it " FRONT SUSPENSION TENSION ROD". 1 Quote Link to comment
Curt Posted May 20, 2014 Author Report Share Posted May 20, 2014 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. Quote Link to comment
ggzilla Posted May 20, 2014 Report Share Posted May 20, 2014 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.
