Each one goes through the same controlled teardown, parts replacement, and testing process.<\/p>\n<\/div>\n<div id=\"wb-what-we-do\" class=\"wordbank-container\">\n<h2>How We Repair Your Unit<\/h2>\n<p>Our repair process for the MOOG 31S020 begins with teardown and mineral bath cleaning to assess all components.<\/p>\n<\/div>\n<div id=\"wb-faq\" class=\"wordbank-container\">\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"faq-accordion\">\n<div class=\"faq-item\">\n<h3><button aria-expanded=\"true\" aria-controls=\"faq-content-0\">Can you help identify what&#8217;s wrong with the unit?<\/button><\/h3>\n<div id=\"faq-content-0\" class=\"faq-content\">\n<p>Yes. Every unit goes through diagnostic testing and we provide an assessment before moving forward.<\/p>\n<\/div><\/div>\n<div class=\"faq-item\">\n<h3><button aria-expanded=\"true\" aria-controls=\"faq-content-1\">Do you offer expedited repair services?<\/button><\/h3>\n<div id=\"faq-content-1\" class=\"faq-content\">\n<p>Yes, rush service is available for an additional fee.

We can restore most units to working condition with tested parts.<\/p>\n<\/div><\/div>\n<div class=\"faq-item\">\n<h3><button aria-expanded=\"true\" aria-controls=\"faq-content-4\">What&#8217;s the lead time on refurbishment?<\/button><\/h3>\n<div id=\"faq-content-4\" class=\"faq-content\">\n<p>Standard turnaround is 1-3 weeks.
