Individual Lower Control Arms with Fitting Position Rear Axle for MAZDA BIANTE CC

These are single CC BIANTE lower control arms rather than pairs, supplied left or right for the position they suit, with the bushes and, where the design uses one, the ball joint already fitted.

They exist for the job where one lower control arm needs replacing and the other does not, which is more common than people expect once you know what causes it.

When a Single Lower Control Arm Is the Right Buy for Your CC BIANTE

There are a handful of situations where buying one arm is exactly right, and buying two would be money wasted.

Impact damage is the obvious one, because lower arms sit below the axle centreline with very little ahead of them, so a kerb strike or a decent pothole reaches them first, and a bent arm is a single sided problem by definition. A few millimetres of deflection in a forged or pressed arm is invisible to look at and completely changes where that wheel sits, which is why an alignment that has never been right since the vehicle hit something is worth investigating before you spend on wear parts.

The other cases are more straightforward than that. One lower control arm ball joint has failed while the other is still tight. One arm is cracked or badly corroded and the other is sound. The opposite side was replaced at some point already. Or you are chasing one specific fault rather than refreshing a whole front end.

Some vehicles also take left and right lower control arms that differ from each other, so an individual arm is the only way to order the one you actually need.

Check the Other CC BIANTE Lower Control Arm Before You Decide

Worth doing properly rather than assuming, because it takes a few minutes and it changes what you order.

With the vehicle safely supported and the suspension unloaded, lever the arm against its mounts and watch for movement at the bush rather than flex in the arm. Do the same on the other side and compare what you see. If one side moves and the other does not, you have your answer. If both move by similar amounts, you are looking at age rather than damage.

Check both ball joint boots while you are there. A split boot on one side with an intact boot on the other points at a single failure, while two perished boots means both joints have been contaminated for a while.

Then look at the mounting eyes on both arms, because a bore that has worn oval will not hold a new bush, and that is a separate reason to replace an arm that has nothing to do with which side it is on.

When You Should Replace CC BIANTE Lower Control Arms in Pairs

If the wear is age related, buy two.

Both arms have covered the same distance on the same roads carrying the same loads, so a perished bush or a loose ball joint on one side almost always means the other is not far behind. Fitting one new arm against one tired one leaves the front end with different amounts of compliance on either side, and the vehicle will pull under braking regardless of what the alignment reads.

The labour argument reinforces that, since your CC BIANTE is already up, the wheel alignment is already being paid for, and the second arm adds far less to the job now than it will as a separate visit in six months.

The short version is that damage gets one arm and age gets two.

What Arrives Assembled in an Individual CC BIANTE Lower Control Arm

Each arm comes with the bushes pressed in, and with a ball joint fitted where the application uses an integral one. The listing states whether a ball joint is included.

That matters more than it sounds, because removing and replacing bushes and ball joints in a suspension arm takes a press, correct diameter tooling and a fair amount of time, and the risk of damaging the arm eye in the process is real. Plenty of people look at that job and decide it is hard to justify.

A complete arm turns it into a remove and replace. You unbolt the old one, bolt the new one in, and the only specialist tool involved is a ball joint separator.

The bushes are the other half of the value. Factory rubber deflects under load even when new and gets worse as it hardens and cracks, so a replacement arm running polyurethane bushes holds the geometry where the alignment set it rather than only when the vehicle is parked.

Why One New Lower Control Arm Can Make Your CC BIANTE Feel Uneven

Worth understanding before you fit a single arm, because it explains a complaint people occasionally have afterward.

A new lower control arm with fresh bushes is rigid. The arm on the other side, if it has covered the same distance, still has compliance in it that the new one does not. Under braking and cornering the two sides now deflect by different amounts, so the geometry changes unevenly and the vehicle can pull or feel slightly off centre even with a correct alignment.

On a vehicle where the other arm is genuinely healthy, that difference is small enough that most people never notice it. On one where the other arm is halfway through its life, it can be obvious, and it is the main reason age related wear is a two arm job rather than a one arm job.

If you are fitting a single arm to a higher kilometre vehicle, it is worth at least replacing the bushes on the opposite side at the same time so both corners have similar compliance.

Ordering CC BIANTE Lower Control Arms by Side and Position

Order by position and side rather than by eye, since a left and a right lower control arm can look near identical in a photograph and be entirely different parts.

Work out which corner you need before ordering, and check the listing for front or rear position as well, since rear lower control arms are listed separately and do a different job on an independent rear end.

If you are replacing a bent arm, measure it against the opposite side before ordering rather than assuming the damaged one is the only problem. A hard enough impact can move more than one thing, and finding that out after the new arm is fitted is a frustrating way to spend an afternoon.

Signs Your CC BIANTE Needs One Lower Control Arm Rather Than Two

• The vehicle hit a kerb or a pothole and the alignment has never been right since
• One side reading out of specification on the alignment printout while the other is fine
• A visibly bent, cracked or damaged arm on one corner
• A ball joint with play on one side and a tight one on the other
• Grease thrown inside one wheel from a split boot, with the other boot intact
• Tyre wear noticeably worse on one front corner
• A previous repair that already replaced the opposite arm
• A mounting eye worn oval on one arm only

If both sides show the same symptoms at similar levels, that is age rather than damage, and you are looking at a pair.

Does Fitting One Lower Control Arm Cost More in the Long Run

It can, and it is worth thinking through before you decide.

The fixed costs on this job are the teardown and the wheel alignment, and they are the same whether you replace one arm or both. Replace one now and the second one later, and you pay both of those twice. Replace both now and you pay them once.

That does not mean two arms is always right. If one arm is bent and the other is genuinely sound, replacing both is buying a part you do not need to fix a problem you do not have.

The deciding question is whether the second arm is likely to need replacing within the next year or two. If it is likely, do it now while everything is apart. If the other side is genuinely healthy and the fault was a single impact, buy the one arm and keep the difference.

Torquing a New CC BIANTE Lower Control Arm at Ride Height, Not on the Hoist

A complete arm bolts into the factory mounting locations and arrives assembled, so this is a spanner job rather than press work.

Support the vehicle on stands and take the spring load off before separating the ball joint, because a joint under load releases suddenly and without warning. Use a proper ball joint separator rather than a hammer, since hammering damages the hub bore and the stud threads.

Torque the inner fasteners with the vehicle back on its wheels at ride height rather than hanging at full droop. Whatever position a bush is clamped in becomes its neutral position, so an arm torqued at droop spends its life twisted and binds from the first kilometre. This is the most common mistake made on control arm work and it costs nothing to avoid.

Fit a new split pin to the ball joint castle nut rather than reusing the old one.

Get a wheel alignment afterward without exception, because replacing a lower arm changes camber and toe immediately, and when you have only done one side the alignment is what confirms the two sides now match each other rather than pulling against one another.
