pwrcat4000 Posted November 14, 2017 Report Share Posted November 14, 2017 Was told by the alignment shop I need Idler arm Upper control arm and strut rod bushings. I am not sure if it is the right terminology I found 2 the Idler Rock auto MEVOTECH MS30909 Supreme Info Front MOOG K9058 {#48530B2000, 48530B9510} Info I found Control Arm Bushings MOOG K9207 {#5451908700} Package Quantity As Shown In Image Info Front Upper Outer; Contains Driver And Passenger Side Bushings Strut rod bushings not showing on rock auto are these the 2 bushings that are under the front bumper This suspension is different than any thing I am used to (seems like a trend) I looked at an old post but all the Photo bucket pictures are gone (also seems like a trend) 1 Quote Link to comment
datzenmike Posted November 14, 2017 Report Share Posted November 14, 2017 The 521 is a torsion bar suspension. Idler arm may come as a kit to replace the , or a complete replacement. Strut rod is also called the tension rod. It's true, there's no point doing an alignment on these worn parts. 2 Quote Link to comment
mainer311 Posted November 14, 2017 Report Share Posted November 14, 2017 The inner or outer upper control arm bushings? The outers are the ones you found on Rock Auto. I replaced mine recently. They work pretty well. If you buy these, get Qty 2, each package contains two bushings, which is enough to do one side. As far as the inners...they are expensive, and hard to find. Some people say they don't go bad, but, mine are definitely bad. They're the same ones used on Roadsters. If they don't get greased regularly, they go bad. They're also an absolute BITCH to get off. 2 Quote Link to comment
banzai510(hainz) Posted November 14, 2017 Report Share Posted November 14, 2017 get under there and wiggle shit around. if not wiggle then dont worry to much abut it yet the upper bushing are EZ to change but there is a way to do it EZer than what I did before.Jack the hub up and spray PB blaster on the bushing and nut ans inside ans turn the bolt or nut which ever one is EZer to get the bolt out and then wack with a hammer with the nut on the get bolt out far as possible before you remove the nut so bolt slides thru the hole I recently did the my center link and tie rods. if front dont shake dont worry about it why you need it alighned? Tires wearing badly If tires OK then dont worry about it. 2 Quote Link to comment
mklotz70 Posted November 15, 2017 Report Share Posted November 15, 2017 The tension rod bushings can be replaced with shock absorber bushings. I would go with rubber over urethane. The upper, outer bushings for the UCA are dirt cheap....buy several sets since they're going to go out in 6mo to a year. I haven't come across a set of upper inners that were so bad I needed to replace them. If you take the UCA off the truck, they're easy to take apart, just spin each half off the cross shaft. The bottom of the dogbone(lower outer control arm bushing) has a fulcrum pin....which is basically the same as UCA inner bushings. Probably not worn enough to cause issues......but it's possible. 2 Quote Link to comment

Seabee Posted October 4, 2018 Report Share Posted October 4, 2018 If you are looking to fix up your tension rods I found that moog (sway bar repair kit) part K7402 comes with x2bushings ( dimensions are correct, tho they feel much firmer than nissans rubber ones), x2 cupped washers, and x1 collared washer. you would need to order 4 of these kits to do front and back of both tension rods AKA strut rods. summit has them for 4.5 bucks each. cheah!!! 1 Quote Link to comment

mainer311 Posted October 4, 2018 Report Share Posted October 4, 2018 Here's a better question: if the threaded end of your tension rod snaps off, where do you find a new one of those? 1 Quote Link to comment
datzenmike Posted October 4, 2018 Report Share Posted October 4, 2018 From another 521. The late '78-'79 620 and early 720 are the same. 521 and early 620 might be. I can look up the part numbers when I get home tonight. 2 Quote Link to comment
Charlie69 Posted October 5, 2018 Report Share Posted October 5, 2018 I have purchased several Mevotech front end parts for my Datsuns that have not fit. I stay with Moog if you can find them. This was another reason I ended up putting a 720 chassis under my 666 520 parts availability. So now I am hoarding 720 parts. It is and endless circle! LOL Quote Link to comment
