Lower Control arm Tools
Both are a waste of money. The UCA tool, while it works well, can be replicated for about $10 at the hardware store
That there is all you need.
The LCA tool, well, maybe it works on some easy ones but if you’ve got a tough case it’ll just strip the bolt.
The 1 3/8” tap and a small press works FAR better. The tap you can usually pick up for around $20 used on eBay. A 12 ton HF press with a coupon and the tap and home made UCA tool and you’re probably not out much more than the Mancini tools. And you’ve got a press that can be used for all sorts of other jobs.
