Wheels of my car make the car bounce back

I am making a old roblox game and i just made a car system simmilar to one from the 2008 era.
but even if i increase the torque of the HingeConstraint Motor it wont ride up the ramp.

Video : Watch New Bloxia 2009 - Roblox Studio 2025-08-18 23-58-43 | Streamable (0:09 seconds in the video)

I have tried increasing the torque or making the ramp more longer.

I can see the car hitting walls and getting stuck until you turn away, I’d imagine it’s the exact same issue. I believe this is caused by the control system not the actual motor? But I’m not exactly sure as I haven’t directly seen the scripts or anything.

Here’s the local script i used

local tool = script.Parent
local player = game:GetService("Players").LocalPlayer
local UserInputService = game:GetService("UserInputService")
local RunService = game:GetService("RunService")

local mouse = nil
local renderStepConn = nil
local inputBeganConn = nil
local inputEndedConn = nil
local ancestryConn = nil
local childAddedConn = nil

local rotationSpeed = math.rad(5760)
local car = nil
local steering = false


local function isValidCar(model)
	return model:IsA("Model") and model:FindFirstChild("Engine") and model:FindFirstChild("ControlCar") and model.Name == "Car"
end

-- Updates the current car reference
local function updateCar(newCar)
	if newCar and isValidCar(newCar) then
		-- Disconnect old ancestry monitor
		if ancestryConn then
			ancestryConn:Disconnect()
			ancestryConn = nil
		end

		car = newCar

		--checks if car got removed
		ancestryConn = car.AncestryChanged:Connect(function(_, newParent)
			if not player.Character or not car:IsDescendantOf(player.Character) then
				disableControls()
			end
		end)
	end
end


local function startSteering()
	if renderStepConn or not car then return end
	local engine = car:FindFirstChild("Engine")
	local remote = car:FindFirstChild("ControlCar")
	if not engine or not remote then return end

	renderStepConn = RunService.RenderStepped:Connect(function(dt)
		
		
		remote:FireServer("Turn",mouse.Hit.Position)
	end)
end




local function stopSteering()
	if renderStepConn then
		renderStepConn:Disconnect()
		renderStepConn = nil
	end

	if car then
		local remote = car:FindFirstChild("ControlCar")
		if remote then
			remote:FireServer("Turn", 0)
		end
	end
end


local function enableControls()
	local character = player.Character
	if not character then return end

	
	for _, child in ipairs(character:GetChildren()) do
		if isValidCar(child) then
			updateCar(child)
			break
		end
	end

	
	childAddedConn = character.ChildAdded:Connect(function(child)
		if isValidCar(child) then
			updateCar(child)
		end
	end)

	mouse = player:GetMouse()

	inputBeganConn = UserInputService.InputBegan:Connect(function(input, processed)
		if processed then return end
		if not car then return end

		local remote = car:FindFirstChild("ControlCar")
		if not remote then return end

		if input.UserInputType == Enum.UserInputType.MouseButton1 then
			steering = true
			startSteering()
		elseif input.KeyCode == Enum.KeyCode.Y then
			remote:FireServer("Move", true)
		elseif input.KeyCode == Enum.KeyCode.X then
			remote:FireServer("Move", false)
		elseif input.KeyCode == Enum.KeyCode.R then
			remote:FireServer("Reverse", true)
		end
	end)

	inputEndedConn = UserInputService.InputEnded:Connect(function(input)
		if input.UserInputType == Enum.UserInputType.MouseButton1 then
			steering = false
			stopSteering()
		end
	end)
end

-- Disable car controls
function disableControls()
	if renderStepConn then renderStepConn:Disconnect() renderStepConn = nil end
	if inputBeganConn then inputBeganConn:Disconnect() inputBeganConn = nil end
	if inputEndedConn then inputEndedConn:Disconnect() inputEndedConn = nil end
	if ancestryConn then ancestryConn:Disconnect() ancestryConn = nil end
	if childAddedConn then childAddedConn:Disconnect() childAddedConn = nil end

	mouse = nil
	car = nil
	steering = false
end

tool.Equipped:Connect(enableControls)
tool.Unequipped:Connect(disableControls)

and here’s the script that the car uses to move :

local car = script.Parent
local engine = car:WaitForChild("Engine")
local turnForce = engine:WaitForChild("Turn")



local remote = car:WaitForChild("ControlCar")
local moving = false

remote.OnServerEvent:Connect(function(player, action, data)
	print("Remote fired:", action, data)

	if action == "Move" then
		moving = data
		if moving then
			car.Part.Script.Enabled = true
			car:WaitForChild("l1").HingeConstraint.AngularVelocity = 55
			car:WaitForChild("l2").HingeConstraint.AngularVelocity = 55
			car:WaitForChild("r1").HingeConstraint.AngularVelocity = -55
			car:WaitForChild("r2").HingeConstraint.AngularVelocity = -55
		else
			car.Part.Script.Enabled = false
			car:WaitForChild("l1").HingeConstraint.AngularVelocity = 0
			car:WaitForChild("l2").HingeConstraint.AngularVelocity = 0
			car:WaitForChild("r1").HingeConstraint.AngularVelocity = 0
			car:WaitForChild("r2").HingeConstraint.AngularVelocity = 0
		end

	elseif action == "Turn" then
		if moving then
			local targetPos = data 
			local desiredCF = CFrame.lookAt(engine.Position, targetPos, Vector3.yAxis)


			
			local gyro = engine:FindFirstChild("BodyGyro")
			if gyro then
				gyro.CFrame = desiredCF
			end
		else
			
		end
	
end


end)

hope this helps!
also for clearance Engine is a part and turnForce is a BodyAngularVelocity.
this might not be the best code but it works on my end!
also i tried to recreate the 2008 feeling but the original tool doesnt work anymore..
