Front lower arm bushings — numbers and sizes

Tags: #control-arm · #bushings · #part-number · #mazda-6-compat · #silent-block

Front lower ("longitudinal"/curved) control arm: FAW part number FC0134J00, sold only as a complete assembled unit — individual rubber bushings cannot be purchased separately from OEM suppliers. Bushings can be manually pressed out and replaced with aftermarket units, but sourcing loose bushings requires matching the exact dimensions ¹. Aftermarket bushings are available via Chinaspare.ru (chinaspare.ru/c/saylentblok-perednego-nizhnego-krivogo-rychaga-faw), with catalog part numbers 61-04503-3X and 61-04504-3X, cross-checked against FAW and other Asian-manufacturer diagrams ². Bushings for the front lower arm are also confirmed available for the facelifted (restyled) X80 via Kitzap.ru; the rear suspension uses similar bushings, and owners have successfully replaced the front set with rear work planned separately ³.

Cross-fit — Mazda 6 GG lower arm: FAW X80 lower control arms cross-reference to Mazda 6 (2002-2007 GG generation) and Mazda Atenza. Part number GJ6A34300 GG. Market price ~3,200 RUB (RU market, October 2024), available on M-Avto and other Russian automotive marketplaces ⁴.

Front control arms — detailed Mazda 6 GG compatibility: both the lower and upper front control arms are sourced from the Mazda 6 GG (first generation); measurements and silentblock dimensions match the Mazda GG parts per Sergey Elibeev. On bent/curved lower control arms, replacement can be attempted without full subframe removal — loosening (not removing) the subframe bolt on one side provides enough clearance. Quoted service labor was 8,000 RUB (RU market, May 2025) (2025-05-04). The Stellox brand part 57-71080a-sx is confirmed as a working lower-arm option ⁵⁶.

Front lower-arm bushing brand comparison (Mazda 6 GG cross-fit, D-42mm): reinforcing the Mazda 6 GG cross-fit noted above (part GJ6A34300 GG) — the original X80 lower control-arm bushing bore is 42mm (D-42mm); Mazda 6 GG or first-generation Atenza (2002-2007) 40mm bushings are a direct fit and are generally preferred over buying a single loose bushing. An even better path is sourcing a complete Mazda control arm. Brand notes from the community: Lynx — decent rubber, standard quality; SH Parts — excellent quality, highly recommended; Suffix — poor-quality rubber; STR and 555 — unreliable/poor rubber. Cross-reference part GJ6A34300 GG on used-parts databases (e.g. Drom) for sourcing ⁷.

Lower control-arm restyle vs. pre-restyle compatibility — unverified, do not assume: whether the restyled (2018+) and pre-restyle lower control arms are interchangeable is not clearly established in the community; the recommendation is to verify part compatibility with a seller before ordering rather than assuming cross-fit between the two body styles (low confidence — no specific fitment difference was detailed) ⁸.

Conical bushing caution — lower ball joint to steering knuckle: when replacing front lower control arms, note there is a conical/tapered bushing installed between the lower ball joint and the steering knuckle. Handle it carefully during disassembly — improper technique can damage the bushing or the knuckle; taking photos before disassembly is recommended ⁹.

Front lower arm bushing — repeated failure and Mazda 6 GG cross-reference with dimensions: one owner asked where to source replacement bushings after having replaced the entire front lower control arm the previous year, only for the bushing to fail again ¹⁰¹¹. Response: the front lower ("straight") control-arm bushing is available from any shop/marketplace, cross-referencing to the Mazda 6 GG (2002-2008) front lower control-arm bushing; dimension photos were shared for verification before ordering ¹²¹³.

Bushing maintenance at very high mileage — repress vs. full replacement, cost comparison (March 2026): at 260,000+ km, lower front control-arm bushings commonly need attention; the community lays out two paths with concrete March 2026 pricing: (1) repress the existing bushings (перепресовывать) — labor cost ~8,300 RUB (RU market, March 2026), preserves the original arms; or (2) replace the entire arm assembly — cheaper overall (~4,000–5,000 RUB per arm) and faster. Quality warning: budget Chinese arms (JD brand) were reported as poor quality, failing within 2–3 weeks of installation — separate bushing part numbers are hard to source on their own, making full-assembly replacement the more practical DIY route. Symptom: shaking/knocking when turning or over bumps indicates bushing failure ^{14151617181920}.

Front lower control-arm anatomy — two arm variants, silentblock/ball-joint locations (March 2026): X80 front lower control arms come in two main variants: (1) a transverse short arm with a single silentblock and integrated ball joint, and (2) a longer transverse arm. Both variants have external and internal silentblock mounts, which is where bushing wear concentrates. At 260,000+ km, these silentblocks should be evaluated; professional testing involves inspecting the upper and lower arms with the vehicle on a lift. As with the maintenance-cost note above, complete arm replacement is generally more practical than bushing-only replacement for DIY work ^162122232425.

Front lower control arm — two different-sized bushings, inner vs. outer: the front lower control arm (передний нижний рычаг) uses two differently-sized bushings that must not be confused: FC0134300-2 (inner/internal, сайлентблок внутренний) and FC0134300-1 (outer/external, сайлентблок внешний) — different diameters, different function, and both should be replaced together as a set when worn ²⁶²⁷²⁸.

Inner lower-arm bushing (sway-bar-link bolt point) — part FC0134300-2: the inner bushing at the front lower control arm's inner pivot (bolt position #22 on the exploded suspension diagram) is FAW part FC0134300-2, available from kitzapchasti.ru ²⁹³⁰.

Front lower control arm bushing — internal diameter mismatch (41mm needed, 40.3mm supplied): buying by part number alone is not reliable — one owner (Egor) ordered the lower control arm bushing and received a part with a 40.3mm internal (bore) diameter, when the X80 needs 41mm; checking other retailers' listings for the same nominal part turned up the same 40.3mm spec across multiple sites, suggesting the mismatch is widespread rather than a one-off packing error ³¹³²³³. The same thread also covers upper front control-arm bushing wear and a dealer-vs-community sourcing dispute — see the dedicated upper control arm card for that part of the discussion.
