Hi guys - I know how it is commonly done including Ian’s great video. Is there a reason why not to use bushing grease instead of softsoap?
So you want the bushing NOT to move or rotate ones installed? I assume that is a reason but wanted to ask. Thanks. |

Thanks. correct. with rubber bushings it's the twisting effect of the bushing that allows rotation. with bearings it's different. hence the reason for soap because it will dry out. @JMitro is correct. Bushing are intended to operate in shear (twisting inside of bushing vs. out side of bushing) and compression only. Rubber has very little tensile strength. Allowing rotation between the bushing and the A-Arm will simply chafe away the rubber in no time. Same is true of the rear control arm bushings unless go you to a solid bushing like Poly or Delrin in which case those materials will withstand rotation between the parts. You want the water to evaporate and leave the surafaces with high friction between ID and OD. water based lubricants only: Soap & water KY Jelly Astroglide Tire bead lubricant can be used in a pinch if the glycerin and water solutions don't work. I rarely have had to resort to this. Get a small dallop from your local tire shop or corner garage that mounts tires. |
