In the process of doing frame repair and I've pulled both passenger rear control arms. They need the bushings replaced and I'd like to open up the flex joints to inspect them since the zerks were dead when I bought the Jeep. Does anyone have the RE3771 and RE3772 tools they'd be willing to loan out if I paid shipping? Or a recommendation for a spanner wrench alternative? I can't see spending almost $50 for tools I won't be using again likely, and it puts me over the budget of rebuilding both rear control arms if I need to buy the flex joint assemblies.
