Happy Friday everyone.

I am more or less a weekend wrencher who’s willing to learn more instead of paying big bucks to a shop.

My plan is to replace upper and lower control arms, as well and front and rear shocks. Optimistically want to have it all done by Monday evening.

I wanted to go ahead and start this thread now because I’m sure I’ll be crying for help.

My biggest concern is the LCAs, and messing up the alignment.

I am considering buying the SPC alignment cam bolts from Auto Zone. I know I need to mark the plate and the frame to make sure the new bolts go into the same place. Is there anything else to be aware of?

Also if you have any other tips to share with a beginner on replacing upper or lower arms and shocks, I would greatly appreciate it.

Going to Harbor Freight to get a few more tools and plan to get started this evening or in the morning.

Replacement parts are 1A auto arms and KYB shocks.

Thanks in advance!

Hopefully you have access to a sawzall, the biggest time increaser for this job IMO is finding the LCA bolts are seized. Running to the store for parts, and having to cut out the old stuff. On my rust-free 4Runner I had to cut out 1 of mine.

Are your front coil overs pre-assembled? That makes installing the fronts easy. If not, you can assemble them using your floor jack. There's a thread on that. Its not bad.

Pay attention to which front spring was drivers vs passenger side. Driver's side is slightly longer, but it's not super obvious. There are two paint marks on each.

Try to orient the end of the spring where it is on the original. Not sure if it really makes a difference. Oh, make sure the spring seat on the front shock (Bilsteins??) isn't upside down. Someone did that once and they were surprised how high their front end was when they got finished.

The original rear shock will probably have to be cut off. The upper half just spun when I tried to loosen the top nut. Most aftermarkets have a nut welded to the top so a second wrench will allow easy removal.

I haven't yet done my control arms, but the long bolt on the uppers can be funny getting room to remove and install. Supposedly, there's a small portion of sheet metal that needs to be bent to allow room, and I think it's tight on the driver's side because of the battery. Total chaos has an older YT video of replacing UCA's on a 2nd gen taco. Same as ours.

Where in NC?

Yep, made sure to buy the shocks preassembled with coil. Thanks for the reminder about the orientation of the shocks.

That is absolutely hilarious about the upside down shock 😂 that is totally something I would do.

I appreciate it! I am in the western mountains of NC… what bout you?

Yea, it's amazing what little things you can goof up on, even when you're trying not to. I'm near Rocky Mount. Work in Raleigh. I love the mts (beach too). Anytime we go, we usually go to the Boone area. I've been mountain biking in Pisgah, but haven't made it that far west in quite a while.

EDIT:
Not sure if it matter now but I found an old thread where someone loosened a hold-down on that AC line blocking your bolt on the pass side. Mentioned here:

Oh nice, Boone is a pretty area. I’m. I’m not too far from Pisgah. Thanks for the link. That’s what I had to do, but got it in there finally.

I am preparing to buy a saw with carbonite blades… nearly everything video and write up I’ve seen had the cam bolts seized. I am trying to get everything this afternoon, but I’m sure I’ll forget something: )

Some helpful videos for ya. I had no experience with any of this type of work myself and was able to UCAs, shocks and springs all around. Take your time. It will likely take longer than you think.

Start here for UCAs and front shocks:

If your front shocks and springs aren’t assembled the no spring compressor method works.

The Toytec website has a video and some helpful tips to make sure you don’t stretch any brake, abs, emergency brake lines.

That is much appreciated! It is sometimes hard to find just the right videos. I’ll try to update this thread as I go along so you guys can learn from my mistakes lol

Ran into this little 12 mm bolt on the ABS bracket… any tips? I can’t even get a 12 mm socket on it.

Try and remove as much of the rust as you can from the head of the bolt using picks, screwdriver and wire brush, etc. then apply some heat with a propane torch to the bolt being careful of not overheating any brake lines, etc., then tap a 6 point socket onto the head with a hammer and then try to remove it, if it does turn a little bit then tighten it some and then try to loosen it some more then tightening it, rinse and repeat until it's removed and throughout this process spray it with a good penetrating oil, what you're trying to do by loosening and then tightening it is to break up some of the rust in the threads and flushing it out with the penetrating oil, you very well may end up breaking the bolt if the rust is as bad as it looks but the way I described above is the only way I can advise you to possibly get it removed.

It's important that you use a 6 point socket on bolts and nuts that are as rusty as that one because they have more surface contact with the hex head of fastener, a 12 point socket will usually round the head of the bolt/nut when they're that rusty.

If the socket slips and rounds off the head then the only thing you can use then would be most likely a pair of Vise-grips.

Edit: Anytime when using a propane torch working vehicles be sure to have a fire extinguisher handy in case something that catches on fire and gets out of control you can put the fire out before it does a lot of damage.

How long do you wanna heat it? I did about 30 seconds. Can’t get a socket to stay on. Vice grips don’t want to work either. I am thinking about drilling or using a nut splitter. Stinks that one little bolt has got this project at a standstill. I can’t get to the UCA bolt without removing this abs bracket.

You can heat it until it's glowing red IF there's not anything else that's going to be an issue when getting it that hot, usually the hotter you can get it the better to help loosen the rust, just an FYI the area you want to heat is the area with the hole, not the bolt itself, what you're trying to do is expand the hole to loosen it's grip on the bolt.

If heat doesn't help then I would go with removing the head of the bolt however you can, drill it, grind it, cutting torch, etc., a "nut splitter" will only work on a nut, it won't do anything on removing a bolt head but deform it.

Okay, I appreciate the advice.

I was trying to heat the bolt itself and not so much the hole. I’ll try that again tomorrow. But should I even bother since I am struggling to get a tool on the bolt head?

I couldn’t tell if there was a nut on there or not, it’s so mangled lol.

Any preference when it comes to drilling, grinding, or cutting torch?

Decided to bypass the AbS bracket for now and use a 19mm wrench to get in there. It was a bit rough, but got the UCA nut off. Now I am trying to figure out how to pull the long bolt out on the passenger side. You can pull it almost out but then it hits a metal line going to the radiator. Tried bending the line slightly but still wouldn’t fit. Don’t wanna bend that line anymore than I have to.
