Replace the front body mount on your VERTEX 10 WIDE with Redcat RER43528. Follow these steps to remove the old mount, fit the new set, and avoid common mistakes.

Quick answer

To install Redcat RER43528, remove the old front body mount from your VERTEX 10 WIDE, clean the mounting area, and secure the new body-side set with the original hardware. Work slowly and check body alignment before tightening fully.

Why the body-side mount matters

The front body mount set (RER43528) is a body-side component for the VERTEX 10 WIDE. It holds the front of the body shell in place and absorbs some impact during normal driving. A worn or broken mount lets the body shift, which can cause rubbing or poor fit.

Because this is a body-side set, it attaches to the body shell rather than the chassis. That means you will be working with the body off the vehicle for most of the installation.

When to replace instead of repair

Replace the mount if the post is cracked, stripped, or missing. A loose body that rattles or lifts at the front is a common sign. If the mount is intact but the body still sits unevenly, check the rear mounts and body clips before buying a new set.

Keep in mind that RER43528 is supplied as one set for the body side. If you also need chassis-side posts or hardware, those are separate parts and not included.

Step-by-step installation

Remove the body shell: Unclip or unscrew the body from the chassis and set it upside down on a soft surface. Common mistake: forcing clips can crack the body; lift gently and keep track of clips. Place small parts in a tray so they do not roll away.
Inspect the old mount: Look for cracks, stripped threads, or missing posts on the body-side front mount. Compare the old part with RER43528 to confirm it matches the mounting pattern. Common mistake: assuming all front mounts are the same; this set is specific to the VERTEX 10 WIDE body side. If the old mount is intact, check body alignment before replacing.
Remove the old mount: Unscrew or unclip the old mount from the body. Keep the original screws if they are in good condition. Common mistake: overtightening and stripping plastic threads during removal; turn slowly and stop if resistance increases. If a screw is stuck, apply light pressure and turn gradually rather than forcing.
Clean the mounting area: Wipe away dirt and debris from the body where the new mount sits. A clean surface helps the mount seat flat. Common mistake: trapping grit under the mount, which can cause uneven fit. Dry the area completely before installing the new set.
Fit the new RER43528 set: Position the new body-side front mount on the body and start the screws by hand. Tighten until snug, then check that the mount sits flush. Common mistake: cross-threading the screws; start them gently and back off if they bind. Do not fully tighten yet; you will check alignment first.
Check body alignment: Reattach the body to the chassis and look at the front gap and height. Adjust the mount position slightly if needed, then tighten the screws fully. Common mistake: tightening before checking alignment, which can cause the body to sit crooked. A quick test fit now saves rework later.
Final check: Press down gently on the front of the body to confirm the mount holds without flexing. Make sure all screws are snug and the body clips engage securely. Common mistake: leaving one screw loose, which can cause the mount to pull out during driving. Recheck screws after the first run.
