Chassis, Steering & Suspension Parts

Chassis, steering and suspension parts carry the load, and they wear according to route conditions rather than mileage alone.

This page lists the chassis, steering & suspension parts we supply for Chinese heavy-duty trucks. The group currently covers 125 part numbers, drawn from these sub-categories: Steering system (39 items); Chassis system (37 items); Suspension system (30 items); Steering linkage (19 items).

What this category covers

Parts in this group include tapered and roller bearings, wheel hubs and wheel bolts, power steering oil tanks and reservoirs, steering gearbox inlet and return oil pipes, drag links and tie rod ends, torque rod bushings and thrust rod assemblies, suspension shock absorbers, driveshaft centre support hangers.

Because these items are ordered by number rather than by picture, the list above is not a catalogue of everything we hold — it is the range of part types that sit in this system. The specific numbers in stock move as stock moves, so the reliable way to check an item is to send us the number.

Vehicles covered

The numbers on this page are listed against SINOTRUK HOWO, SHACMAN Delong, FAW Jiefang, FOTON Auman, DONGFENG, CAMC Hualing.

Typical applications are SINOTRUK HOWO (HOWO, HOWO A7, T7H, TX, Steyr, SITRAK); SHACMAN Delong (Delong F2000, F3000, M3000, H3000, X3000, X5000); FAW Jiefang (J5P, J6, J6P, J6L, J6M, JH6, J7, Hanwei); FOTON Auman (Auman ETX, GTL, EST, Aumark); DONGFENG (Tianlong, Tianjin, Kinland, Kingrun, EQ153 chassis); CAMC Hualing (Hualing, Valin, Xingkai, JAC Gallop).

The same system can be built differently across model generations, so two trucks with the same badge may not take the same part. Always confirm against the part number or the chassis number.

How to identify the right part

Before ordering, check these three things: axle rating and chassis series (for example EQ153, 153 bridge, 457 axle), bearing bore and width, pipe thread and banjo bolt size.

If you do not have the part number, send photographs of the old part from two angles and the chassis number. In most cases we can identify the correct number from those alone.

Sample part numbers in this category

Examples of numbers in this group: LG7118320024, AZ9725521384, AZ4075410040, AZ4071410051, 712W47301-0133, WG9100032314, AZ9631521175.

Direct replacement for OEM part no. LG7118320024.

Where a single number covers more than one specification, the variant is listed on the product page, and we will confirm it with you before the order is packed.

How to order

1. Send the part number

Give us the number stamped on the old part, or the number from your parts book. If you only have the chassis number, send that instead — we will look it up.

2. Tell us the vehicle

Tell us the make, model and, where possible, the year of the truck. The same system can use different parts across model generations.

3. Confirm the variant

Where a part number covers more than one specification, we will send you the options with their measurements so you can pick the one that matches your truck.

4. Receive a quotation

We reply with price, packing and shipping options for your destination and quantity. No price is published on this site because freight and quantity change the figure for every order.

5. Approve and ship

Once you approve the quotation we pack the goods, send photographs of the packed cartons, and hand over to your forwarder or ours.

How these parts fail, and when they are replaced

Wheel bearings fail gradually and announce themselves as a rumble that changes with steering load. Louder on one side in a turn points at the loaded bearing.

Torque rod bushings perish before they tear. A bushing that has gone soft produces a clonk on load reversal, which is frequently mistaken for a suspension fault.

Steering oil tanks crack at the mounting feet or at the return pipe union. A tank that weeps at the foot is usually a fatigue failure rather than a pressure failure.

Tie rod ends develop play that shows first as vagueness at highway speed rather than as a clonk at low speed.

Driveshaft centre support hangers fail at the rubber, and the first symptom is usually a vibration at one particular road speed.

Part numbers change between model generations

Part numbers change across model generations even when the visible part looks the same. A housing may be carried over while the connector, the thread or the mounting ear changes, and those are the differences that decide whether a part fits. This is why we ask for the number, and why a part that looks identical to the old one is not accepted as proof that it is the right one.

Packing

Parts in this group are packed according to what they are. Rigid castings travel in cartons with corner protection; pipes and cables travel straight rather than coiled, because coiling sets a bend that is difficult to remove; lamps travel individually wrapped. If the packing needs to suit a particular route or a particular forwarder, tell us when you order and it will be arranged.

Questions buyers ask about this category

How do I know this part will fit my truck?

Check the part number first — it is the most reliable identifier. Then check the vehicle details listed on the product page. If the number on your old part matches, the part fits. If you are unsure, send us the chassis number and a photograph of the old part.

Can I order a single piece, or do I have to buy in bulk?

Both are possible. Consolidating several part numbers into one shipment usually reduces the freight cost per item, so workshop and fleet buyers commonly group their requirements into a single order. Ask us for a quotation on the quantities you actually need.

Is this part made by the truck manufacturer?

No. It is an aftermarket replacement part supplied by SAIWEN, an independent supplier, and it is not made by the truck manufacturer. It is intended to be used in place of the corresponding OEM part.

What information should I send with my enquiry?

The part number, the truck make and model, the quantity, and your destination port or city. A photograph of the old part helps when the number is worn or unreadable.

Can you supply the parts for a whole system rather than individual items?

Yes. Buyers rebuilding a gearbox, a braking circuit or a cab tilting system often order the complete set of related items together. Send the list and we will quote it as one order.

Do you publish prices on the website?

We do not publish prices, because the delivered cost depends on quantity, packing and destination. Send your requirement and we will quote it directly.

Are the part numbers on this site the ones I should search for?

Yes. The numbers shown are the reference numbers used to identify each part. Search by that number, or send it to us, and you will reach the correct item.

How do I identify my axle?

By the axle rating and the series stamped on the housing, for example the 153 or 457 series. Send the part number and the axle identification together.

Are bearings supplied as sets?

It depends on the number. Send the number and we will tell you whether the cup and cone are supplied together or separately.

What if my number has been superseded?

Send the old number. Where a number has been replaced we will tell you the current reference rather than leave you to guess.

Sending an enquiry that gets a single quotation

A good enquiry takes two minutes to write and saves a fortnight of correspondence. It states the part number, the truck make and model, the quantity, and the destination. Where the number is uncertain it includes a photograph. Where the requirement is a repair rather than a single item, it lists everything intended to be replaced in the same job. Buyers who send the full list in the first message generally receive a single quotation that covers the whole repair, instead of a sequence of quotations that each need a separate freight calculation.

If your number does not match

If the number you send does not match anything in our catalogue, that is not the end of the enquiry. Numbers are frequently superseded, and a number that has been replaced may still identify the correct current reference. Send the old number anyway, together with the vehicle details, and we will tell you what we can and cannot match. We would rather tell you that a number is not available than send a part that will not fit.

Related categories on this site

Buyers working on this system usually order from other systems in the same job. All of the categories are reachable from the product list, and the category pages are linked from the main navigation, so you can move between them without going back through the home page.

Before you send the enquiry

If you are working on a chassis or steering problem, send the axle rating as well as the part number — the same part number can be listed against more than one axle specification.

This is an aftermarket replacement part and can be used in place of the corresponding OEM part.
