Frequently breaking rear sway bar - Any solutions??
So, recently observed my rear sway is broken yet again, i dont wheel, though go offroad infrequently to exercise the 4wd, i have rancho quick lift struts with 1.75inch lift at the front, and 1.5inch lifts at the rears.
am puzzled at the frequent breakage, so my questions are
1. Could i weld the broken sway bar and reuse?
2. Are there beefier sway bars i cud install, as i noticed the sway bar is just a hollow metal tube
3. If the above 2 scenarios are wrong - ie would transfer the stress to the next weaker link. what is the next weaker link that this stress would be transferred to???
4. I am not comfortable running without rear sway bars, cos i pulled off/broke one of my rear brake lines last time, due to too much articulation -

Had a similar issue on a Subaru, yeah I know
Ended up using a oversize 22mm VS 19mm diameter sway bar. Then ended up replacing the sway bar links annually. The increased stiffness really helped handling though.
Regarding yours, there has got to be something going on for two stock bars to fail. I'd look into that before putting another sway bar on.

this is just a guess but that 1.5" rear left could have offset your rear axle just enough to put that pressure on the sway bar links were they are breaking. An adjustable aftermarket panhard bar like this one would align the rear axle as it was before the lift.

I have the ADDCO bars on my V8 '05. They are monstrously stiff. They give the truck way more confidence than it is due in corners.
My passengers in the rear seats no longer clunk heads together when driving around, which was why I got the ADDCOs.
They also eat endlinks for breakfast, it seems... replacing another set tomorrow.
However, the panhard bar @jrm recommended is a better place to start than a stronger sway bar, I think.

Update:
Upon inspection, the endlink itself was fine as were the bushings. However, the OEM endlink had actually wallowed out the hold in the sway bar and thus had become loose and mobile in the hole (even though the bolt was tight).
There's alot of force transmitted through the sway bar, so it's no surprise this happened. The shop cut off the (relatively new) OEM Toyota endlinks and replaced them with MOOG links, which do not appear to suffer the design flaws the Toyota endlinks did. I had them add grade 12.9 washers to protect the bar from being ripped up.
The MOOG endlinks have a much larger ball housing with a greaseable zerk fitting. The shaft is WAY bigger. And the bar-end bolt has a nut fitting cut into the ball side of the bolt to hold with a wrench while installing and removing the [much larger] nut.
Which endlinks to buy? atleast on purchase inspection, the MOOG is far superior to the Toyota. We'll see how they hold up to a heavy flogging up some mountain roads and through winters.

If you lifted the rear at the coils but did not extend the sway-bar end links it maybe causing more tension on the bar.
You can use 2nd gen 4runner end links. They are 1" longer, and on the cheap.
A couple other heavy duty versions to be had also.

You could just take the whole thing off, throw it in the trash and simply get stiffer rear springs. I'm not exactly sure why anyone wants a rear sway bar for off road. The entire point of going off road is to let the suspension articulate and the sway bar prevents this.

I Have broken mine as well. I now disconnect it every time I go off-road and reconnect when im doing pavement time. Eventually as DUFFDOG said, ill be getting stiffer springs and removing it all together.
I usually just disconnect the endlink from the body side on top.. remove the bushings fold the endlink down with the sway bar and let it move around.. ive done it several times.. and then easily reconnect it when im done.. DOesnt interfere with anything, under heavy flex it clanks a little bit on the lower links..

so would try the option of using 2nd gen endlinks. am thinking of welding the broken sway bar and use it with the 2nd gen end links for a while, lemme see how it holds up

I went with these, nice and tight and sets the bar level with the ground like factory. You have to drill out the bar to 13mm for the bolt.

Frequently breaking rear sway bar - Any solutions??
Sorry, I don’t have any info that can help you, but was wondering how you like the Rancho Quick Lift and if you used their spacer in the rear or went with a different set up.

That Daystar looks like the same/identical rear 1.5" spacer as the Rancho branded one.
On car-part.com you can get that rear sway-bar for $75-$150.
