What This Product Does
The isolator forms a compliant interface at its designated rear axle mounting location. Its rubber construction cushions adjoining assembly parts, accommodates minor movement and reduces the direct transfer of vibration through the side-section or carrier connection.
Functions
- Separates associated components at the specified mounting point
- Cushions minor movement within the rear axle assembly
- Limits vibration passing through the mounting interface
- Supports the intended location of the side-section or carrier components
Technical Details
- Manufacturer: Porsche
- Part number: 99633138500
- Porsche catalogue description: rubber mounting
- Alternative diagram description: rubber bush or rubber isolator
- Installation area: rear axle side section, side part, bracket or carrier
- Diagram quantity: six per applicable assembly
Symptoms of Fault
- Rubber showing splits, compression, hardening or distortion
- Knocking or movement around the rear axle mounting area
- More vibration entering the body structure
- Looseness between associated carrier or side-section components
- Rear suspension behaviour that changes as the mounting moves under load
Why Replacement Matters
Deteriorated rubber may cease to isolate the connection or hold adjoining parts in their intended relationship. Renewing the mounting helps reinstate the compliant interface specified for the assembly. The surrounding bolts, locknuts, cross members, transverse struts and side sections should also be inspected, since looseness or wear in these parts can produce similar symptoms. An appropriate geometry check may be required after substantial rear axle or suspension work.
FAQs
- Is this an original Porsche component?
Yes. Porsche lists 99633138500 as a rubber mounting in its parts catalogue. - Where does the isolator fit?
It appears in rear axle side-section, side-part, bracket and carrier diagrams for applicable 996 and 997 models. - How many are shown in the assembly?
The supplied exploded-diagram data specifies a quantity of six for each applicable assembly. Confirm how many are needed for the particular repair. - Should other components be checked?
Yes. Inspect the adjacent hardware, cross members, struts and mounting areas for corrosion, damage, movement or wear before installation.
