<html><head><meta http-equiv="content-type" content="text/html; charset=utf-8"></head><body dir="auto">Hi Jeff,<div>I ended up replacing/upgrading my worn out TR4A IRS differential plus Richard Good rear hubs and CV style half shafts by myself. I would definitely recommend buying or borrowing a transmission jack. I picked up one from Harbor Freight for less than $100.00.</div><div>It was definitely worth it. Also look for a diff with a 3.688:1 ratio, which is fairly common. I also replaced the pinion and stub axle seals before I installed it.</div><div>Dave Connitt<br><br><div dir="ltr">Sent from my iPhone</div><div dir="ltr"><br><blockquote type="cite">On Jan 27, 2022, at 12:31 PM, Jeff Nathanson <jeffn@msystech.com> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr"><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><meta name="Generator" content="Microsoft Word 15 (filtered medium)"><style><!--
