Default Ucf10/11 Suspension Refresh

Hey folks,
I'm trying to gather parts for a complete suspension refresh on my '91 Celsior. I am able to find most of the front suspension components, minus the upper control arms. Any good aftermarket solution for those? Or able to get the balljoints/bushings seperately?

Having a hard time finding the rear suspension components:
48725-50030 | Bush for lower control arm
48710-50010 | Toe-control link
Also looking for the upper control arms, or the bushings and balljoints to replace.
Also looking for the bushing and balljoint that are in the knuckle.

Anyone have any sources or new-old stock parts they're will to sell?

For the front upper control arms you will just have to go aftermarket and replace when they wear out. The bushings are replaceable but there is no ball joint replacement option as far as I am aware.

In terms of the rear your options are polyurethane for 48725-50030.
As for 48710-50010 there is nothing other than aftermarket. I installed Megan brand control arms, they use a pillow ball bushing instead of rubber, no noticeable NVH increase.
For the rear upper control arms you can replace both the bushings and ball joint. You have a few polyurethane options for the bushings, I recommend superpro. For the ball joint you can use a front upper ball joint that fits a 2005-2020 Toyota Tacoma.

The bushings in the rear knuckle you will have to go aftermarket. There are some ebay rubber options along with polyurethane.

I found a couple of listings on ebay for the rear knuckle bushings.
I'm assuming that the UCF20 Toe-control links wont fit as the suspension is a bit longer? Those are still available new and if they can fit, I'd rather use those instead of poly bushings.

Thanks for the rear-upper balljoint reccomendation, I'll check out the Tacoma ones

I do not think they will fit. The rear subframe is totally different in the UCF20. The only way you will find out is by spending the money to order them and then see if they fit or not.
