BALL JOINTS: Sankei 555 (Moog/Raybestos) Poor Quality/Design Flaw??? My Findings...

I ran nothing but Moog on my last two trucks ('00 Explorer, '86 4Runner) and was very happy with them, but I think I'm convinced. I won't put Moog on the '99.
 
As a side note, if you get Toyota parts, get the Tacoma version instead of the 4runner. Taco stuff has a little more beef to it.

Note the shank difference on the tie rod ends

Sankei 555 is NOT the OEM manufacturer of UBJs. This has been covered before and I reached out to Sankei directly and here is there response:

Dear Mr. Mike,


1. Sankei is not an OEM supplier but has been supplying our suspension and steering parts to North American Aftermarket through our customers for more than 45years.

2.Our products are designed and manufactured with our own engineering and technical standards, which are “equal” or “exceeding” to OEM quality. In fact, we have a high reputation as a qualityproduct manufacturer and supplier.

3. Sankei does not have different grades of product, though in these days, some American parts manufacturers and distributors have so called the “Premium” and the “Economy” which is lower grade of product coming from low cost countries. Our Sankei products are supplied for the aftermarket as the “Premium” through our customers.

Best regards,
Taro Yamazaki

As for using Tacoma parts, I understand this effects the turning radius on the 4runner.
 
Yes, using Tacoma parts will increase your turning radius. In my opinion, it's not worth using the Tacoma parts. If they are any stronger, would be very minimal, it's not worth the increase in turning radius.
 
I'm sure some guys already know this, but FWIW I was chatting with the guys at Napa when picking up some replacement LBJ's and they mentioned that Spicer makes their premium chassis line of parts (not the Master ride series, Napa Chassis parts). Their premium line seems pretty good, and has gotten good reviews here. Actually the Napa Chassis line was the same price as the duralast LBJ at autozone.

The casting is probably not the failure point for most LBJ's, I think it's usually the ball.

I agree.

On another note, even if the Tacoma parts provided identical turning radii. Who is to say that they are really effectively stronger. There are a lot of unconsidered variables to claim this. Perhaps the Tacoma components cross section is thicker in places that aren't even high stress areas so it might not matter. The thinner 4Runner components could actually be a more refined design that removes unnecessary material to save money on raw materials or they could even be slightly different alloys.:noidea:

It's been discussed on here on a few threads. Something to do with the LBJs coming into contact somewhere during the turn, thus Messing with the radius. Do a search and you should find it.

Gotcha. I haven't had any issues, but my entire front susp, is Tacoma so it all works together just fine.

Spicer does make some of Napa's premium chassis components but whatever is in their system for premium 4Runner ball joints are definitely identical to 555 Sankei (atleast at the Napa I went to). I am not sure how the supply chain system works but it appears Moog, Napa, Raybestos, Beck/Arnley...they all likely just rebrand and supply the 555 Sankei part. For the lower ball joints, I haven't actually found any variety in manufacturers other than OEM or Sankei/555. But maybe someone can correct me...
 

I have the 555 Tacoma LBJ and OTRE. For me, the tie rod hits the sway bar moumt, leading to reduced turning (significant) and a spongy feel at lock because it is flexing the rack (not good). I need to crawl under there and clearance the sway bar mount a bit.

If I remember correctly, the shank of the ball joint is significantly larger, the ball may be as well. If the ball is larger, This would increase the bearing area of the ball and increase strength.

I was just under my truck this weekend and noticed that the boots on the LBJ are very dry and cracked. Both the LBJs and OTREs are very corroded, even though they have less than 10k miles and I'm not in a salt zone (Oregon).

I bought the Raybestos parts (which ended up being the 555 part) with a lifetime warranty that is supposed to include labor. Has anyone attempted go redeem this? I bought them through rockauto and the item number isn't recognized any longer.

For the zillionth time - ALL - "555" is not a part type. It is a metal casting impression. At most it means that they used a Toyota part to cast the replica.

Basically 555 means nothing for you the consumer. You bought a raybestos part .... Aka not Toyota/OEM. 555 is not a parts maker lol. That Chinese part is just like the rest and that's why it broke at 10k miles.

Buy Toyota / OEM Ball Joints! They are different than these knock offs

I have had no issue with anything hitting/rubbing/binding. Nor does it steer any different, or steer more or less. All of my front end is Tacoma it all works together fine. I'm also running a bit more lift than most and a larger tire as well. Not sure if that has anything to do with it or not. I was merely showing the differences between the different parts. If people don't want to run them...Don't. All the issues that people have brought up I have experienced none of them.

The balljoint is the same size Tacoma and 4runner. The Tacoma has a larger outer tierod end that must be used with the Tacoma balljoint.
 
So not to dig up an old thread, but I can't seem to post a new thread, and I've searched & read a bit, but don't see this answered anywhere directly.

Is there any way to identify a ball joint's manufacturer by looking at it? If it is OEM, will it definitely have the 555 cast on it? And where does one look for that casting? If it doesn't have the 555 casting, does that mean it is not OEM??

Just forget about the "555" altogether. It doesn't mean anything.

There's so much Chinese knock-off stuff on the market right now that the only way to know what you have is to buy it directly from the manufacturer.

Even the eBay and Amazon stuff that's being sold as OEM is suspect in a lot of cases.

I work in automotive manufacturing, and this is a big problem right now.

okay, thanks. I don't see the 555 on them, so I got a little worried. It's a sale on this forum, so I'm hoping it's an honorable sale.
